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.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
