Question

on which condition force acting on a moving charge in uniform magnetic field will be minium​

Answer 1

Hi Mate,

magnitude of force experienced by a charge moving with velocity v is given as:

F = qvB sin∅

where theta is an angle between direction of velocity (V) and direction of magnetic field (B).

And we know minimum value of sin∅ is zero. that means force experienced by a charge is minimum when it moves parallel or anti parallel to direction of magnetic field.

Good Day...!

Answer 2

Answer:

Here is your answer

Explanation:

The force acting on the charge will be minimum when the magnetic field is parallel to the charge. This is because force= ILB× sin theta

since theta is 180°

sin theta will be zero and hence the force will be zero or minimum
