Question

The diagram shows a negative charge moving in a magnetic field. In which direction is the magnetic force acting on the charge? Right, left, into the screen, or out of the screen

Answer 1

its b on edge \(-u-)/

Answer 2

By right hand rule direction of force will be towards left

Step-by-step explanation:

Here we know that force due to magnetic field on moving charge is given by

`F = q(\vec v * \vec B)`

here as we can see the figure

v = velocity of charge coming out of the plane

B = magnetic field vertically downwards

q = negative charge

so from above equation of force we will have

`F = (-q)[v(\hat k) * B(-\hat j)]`

`F = -(qvB)\hat i`

so direction of force will be towards left
