Question

Joann has rubbed a balloon with wool to give it a charge of -1.0 x 10-6 C. She holds the location of charge on the plastic golf tube at a distance of 50.0 cm above the balloon. Determine the electrical force attraction between the golf tube and the balloon.

Answer 1

$F=kqq/x^2=9\cdot10^9\cdot1\cdot10^{-6}\cdot1\cdot10^{-6}/0.5^2=0.036\ (N)$
