If a charged particle kept at rest experiences an electromagnetic force,

If a charge particle kept at rest experiences an electromagnetic force, (i) the electric field must not be zero (ii) the magnetic field must not be zero (iii) the electric field may or may not be zero (iv) the magnetic field may or may not be zero

If a charged particle at rest experiences no electromagnetic force, then The electric field must be zero

If a charged particle at rest experiences no electromagnetic force, then electric field in that region

If a chraged particle at rest experiences no electromagnetic force, (i) the electric field must be zero (ii) the magnetic field must be zero (iii) the electric field may or may not be zero (iv) the magnetic field may or may not be zero

A charged particle moving in a magnetic field experiences a resultant force

When a charged particle is projected perpendicular to the magnetic field, the force acting on the charged particle is……………of the radius of circular path but…………….the speed of the charged particle.
