You hold a ruler that has a charge on its tip 4 cm above a small piece of tissue paper to see if it can be picked up. The ruler has −14 µC of charge. The tissue has 1 g of mass. What is the minimum charge required to pick up the tissue paper?

Answer: ___ µC

Expert Solution

We have to overcome the force of gravity (m.g) to pick up the paper. So to find the minimum charge required we will equate electrostatic and gravitational force.
