Question

Statement 1 : If a charged particle is released from rest in a
region of uniform electric and magnetic fields parallel to
each other, it will move in a straight line.
Statement 2 : The electric field exerts no force on the particle
but the magnetic field does.

Answer 1

Explanation:

Due to electric field, the force is

F

=q

E

in the direction of

E

.

Since

E

is parallel to

B

, the particle velocity

v

(acquired due to force

F

) is parallel to

B

.

Hence

B

will not exert any force since

v

×

B

=0 and the motion of the particle is not affected by

B

.
