Answer to Question #341657 in Physics for James

Question #341657

A tiny 0.8g ball carries a charge of magnitude 10μC. It is suspended by a thread in a

downward 500N/C electric field. What is the tension in the thread if the charge on the ball is

positive?

Expert's answer

"T=mg+qE\\\\\n= 9.8*0.8*10^{-3}+10*10^{-6}*500\\\\\n=0.0128\\:\\rm N"
