If the charge of a particle doubles, what happens to the force acting on it?
it doubles
it gets reduced by a factor of two
it stays the same
a charge exerts a negative force on another charge. does that mean that:
both charges are positive
both charges are negative
the charges are of opposite signs
explain this throughly!

Explanation:

(1) The force that exists between charged particles is electrostatic force. It is given by :

Where

q₁ and q₂ are charges

r is distance between charges

If the charge of a particle doubles, the electric force doubles. So, the correct option is (a) "It doubles".

(2) A charge exerts a negative force on another charge. Negative force denotes the force is attractive. It means that the charges are of opposite sign. So, the correct option is (c) "the charges are of opposite signs".

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
