Force on negative charge is opposite to that on a positive charge. Pls explain.

Dear Student

let us take two plates of opposite charges and put the test charge in between the plate.
once keep the positive charge and once keep negative charge inside the field.
If a positive charge keep inside the field it will be attracted towards the negative plate and repel by the positive charge.
 

 

If a negative charge is placed in between the plates it will repel negative metal plate (like charges repel) and move towards positive metal plate. force will be in vertically upwards direction.

This shows that the force in the differet charge will be different.


Regards
