Magnetic Effect Of Current NAT Level - 1 - Question 7

A particle having a charge of 10.0µC and mass  moves in circle of radius 10cm  under the influence of a magnetic field of induction 1T. When the particle is at a point P, a uniform electric field is switched on so that the particle starts moving along the tangent with a uniform velocity. The electric field (in  V/m) is


Detailed Solution for Magnetic Effect Of Current NAT Level - 1 - Question 7

Correct answer is  10.0 V/m

  • When the particle moves along a circle in the magnetic field B, the magnetic force is radially inward.
  • If an electric field of proper magnitude is switched on which is directed radially outwards, the particle may experience no force.
  • It will then move along a straight line with uniform velocity.
