Question

A negatively charged particle is situated on
straight line joining two other stationary particles
each having charge + q. The direction of the motion
of the negatively charged particle will depend on
1) the magnitude of charge
2) the position at which it
is situated
3) both magnitude of charge and its position
4) the magnitude of +q​

Answer 1

Given that,

A negatively charged particle is situated on  straight line joining two other stationary particles  each having charge + q.

We need to find the direction of the motion  of the negatively charged particle will depend on

According to the Coulomb's law,

The force acting on any two charged particles is given by,

$F=\dfrac{kQq}{r^2}$

Where, Q and q = charges

r is the interparticle distance between the particles.

Thus, the direction of motion of the negatively charged particle will depend on the force acting on it.

Or the direction of motion of the negatively charged particle will depend on the position where it is placed in between the 2 positively charged particles

Hence, (1) and (2) is correct option.
