Question

A particle of charge 'q' and mass 'm' is moving along the x-axis with a velocity 'V' and enters a region of electric field 'E' and magnetic field 'B' as shown in the figure below. For which figure the net force on the charge may be zero? 

Answer 1

#Correct answer is (B)or 2nd fig. , You can check using right hand thumb rule of palm rule.

#In right hand thumb rule curl fingers from direction of V to B and where thumb points that will be your direction of magnetic force.

#In palm rule point all fingers in direction of B , thumb in direction of v and where palm points that will be your direction of Magnetic field.
