Value of k in coulomb's law depends upon

magnitude of charges

distance between charges

both A and B

medium between two charges

Two charges are placed at a certain distance. If the magnitude of each charge is doubled the force will become

1/4th of its original value

1/8th of its original value

4 times of its original value

8 times of its original value

If an electrons is allowed to move along the field in a non uniform electric field then it will follow

Spiral path

Straight line

Curved path

Circular path

If F is force acting on test charge qo, electric field intensity E would be given by

E = F - qo

E = F/qo

E = F + qo

E = qo/F

5 × 109 Nm²C-2

7 × 109 Nm²C-2

8 × 109 Nm²C-2

9 × 109 Nm²C-2
