Objects 1 and 2 attract each other with a electrostatic force of 36.0 units

​

F' = 9F

Explanation:

The complete question is "Objects 1 and 2 attract each other with a electrostatic force of 36.0 units. If the charge of Object 2 is tripled, then the new electrostatic force will be _____ units".

The electric force is given by :

If F = 36 units,

If charges are tripled, q₁' = q₂' = 3q₁ and 3q₂

So,

So, the new force becomes 9 times of the initial force.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
