A particle of change 'q' and mass 'm' is moving with a velocit towards a large screen in the Y-Z plane at a distance 'd'. if there is a magnetic field , the minimum value of v for which the particle will not hit the screen is:
Option: 1
Option: 2
Option: 3
Option: 4
As velocity and magnetic field is perpendicular to each other So particle will perform uniform circular motion in x-y plane
And its radius is given as
So if the particle will not hit the screen then
