Solution

The correct option is D Exerts a force, if the particle is moving perpendicular to the direction of the field.
Answer is D.

A charged particle moving through uniform magnetic field, experiences a force due to magnetic field and moves perpendicular to the direction of magnetic field.
The expression is given as,
F=qV×B
where,
F Magnetic force
q charge
V Velocity of the moving charge
B Magnetic field
The force exerted is always perpendicular to the plane formed by V and B. Oppositely directed forces exerted on oppositely charged particles will cause the particles to move in opposite directions. Therefore, option D is the answer.
