Question

which one is correct please give explanation​

Answer 1

Answer:

The right answer is positive z - axis.

But it’s not in the options.

Explanation:

Since the particle is placed in negative z - axis it must be negatively charged.

The force acting on a negatively charged particle is opposite to that of the electric field.

Answer 2

Answer:

Rotation motion

Explanation:

★ We know that ;

Torque = Force × radial vector

Torque => + Z - axis

Radial vector => Negative z axis

Force => ??

For perpendicular distance

and max torque

all the vector should be perpendicular

so ;

Force should be act in Negative y direction .
