An isolated metal ball has a charge on each square metre of $7.4 \times 10^{-7}\ \text{C/m}^2$ and a radius of $8.5$ cm. What is the potential of the ball compared with infinity?

← All Quizzes

← A sensitive meter is kept in a closed metal box, and a charged cloud passes near the box. Why is the field inside the box almost zero?Two metal balls of radius 3.0 cm and 9.0 cm are far from each other and joined by a thin wire. What is the ratio of the field at the surface of the smaller ball to the field at the surface of the larger one? →
