Using coulombs inverse square law, if the charges of two similarly charged spheres increases, what would happen to the value of a? (in this experiment we moved a charged sphere closed to second one and observed how this second one moved away) a is fromt the equation fcoul= a/r 2

The value of A will increase as you increase the charges.

Explanation:

A is actually kq1*q2. So if you increase the charges, A will also increase. The big increase comes if you make r smaller.

Increased charges is a direct variation. As the charge increases the value of A increases. As the charges decrease, the value of A decreases.

r is an inverse variation. As r increases the force decreases. As r decreases the force increases. R does not affect a.

the bal will not change its velocity.
