Question

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

Answer 1

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

Step-by-step 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.
