What is magnetic force measured in? - Socratic
Dec 22, 2014 · Force is always measured in Newtons(N) be it magnetic or electrical or mechanical. The unit of force won't change. What does change is the unit of the associated field. For e.g: Magnetic field is measured as Tesla(T) electric field is measured as Newtons/coulomb(N/C). So various fields have various units and specific formulas that relate the field intensity to the force experienced but force ...
What unit of force is used in the universal gravitational ... - Socratic
Jun 13, 2016 · That depends on the unit system used, but in the SI (Systeme Internationale) system, units are as shown here: The gravitational constant G=6.67xx10^-11 m^3 kg^-1 s^-2. Alternatively, and equivalently, the units can be written as Nm^2kg^-2, in which case the force unit is the newton (N). The gravitational force expression is: F=(Gm_1m_2)/r^2 If we rearrange to make G the subject: G=(Fr^2)/(m_1m ...
What are field forces in physics? + Example - Socratic
Mar 6, 2018 · When a body exerts an influence into the space around itself, we say that the body creates a " field " around itself. I tried to look up "field forces" but found nothing related to Physics given that phrase. I will assume you mean "force fields". When a body exerts an influence into the space around itself, we say that the body creates a " field " …
The Electric Field - Physics - Socratic
May 17, 2014 · A force field is a way to picture the effects that electric charges have on one another. Instead of talking about the force that a positive charge exerts on an electron, we can say the charge creates a force "field" in the empty space around it. An electron put down at any place in this force field is pulled towards the positive charge; a positive charge set down at the same place is pushed away.
Why is the electric field negative? - Socratic
Jul 26, 2015 · Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field. Electric fields generated by electric charges originate from positive charges and terminate from negative charges. An electric field exerts on electric ...
What does it mean to say that the gravity of the Earth is 9.8 m/s2?
Jan 27, 2016 · The acceleration of gravity (also referred to as the gravitational field strength) at the surface of the earth has an average of 9.807 m/s^2, which means that an object dropped near earth's surface will accelerate downward at that rate. Gravity is a force, and according to Newton's Second Law, a force acting on an object will cause it to accelerate: F=ma Acceleration is …
How does current affect magnetic force? - Socratic
Aug 22, 2014 · Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. The relevant equation for the magnetic force acting on a straight current carrying conductor in a uniform magnetic field is: F=BILsintheta So the force is directly proportional to the size of the current. Practically this means the following: If …
Magnetic Force - Physics - Socratic
Apr 26, 2014 · A magnetic force is the attraction or repulsion that arises between electrically charged particles because of their motion; the basic force responsible for the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; and both electric and magnetic forces exist among moving electric charges. This force is usually measured in ...
Derive the charge to mass ratio (e//m) for an electron? - Socratic
Jan 29, 2018 · LORENTZ FORCE & MAGNETIC FIELD This kind of motion is described by: \mathbf(vecF_B = qvecvxxvecB where: q is the charge of the moving particle. vecv is the velocity of the particle, tangent to the circular path. vecF_B is the magnetic force imparted by the magnetic field, perpendicular to the velocity of the particle.
What force will a proton experience in a uniform electric field …
3.2 xx 10^-14N A proton has a charge of 1.6xx10^-19C. Therefore, by F = QE where F is force, Q is charge and E is electric field strength, F = 1.6 xx 10^-19 xx 2 xx 10^5 = 3.2 xx 10^-14N
