A $91$ V battery is joined to two flat metal sheets, which face each other across $1.3$ cm of air. How strong is the field in the gap?

← All Quizzes

← Seen from 0.72 m away, a charged pith ball acts like a point charge of 8.4 nC. Find the electric potential at that distance.A student says: a negative charge, released from rest in an electric field, always moves to a point of lower potential, because positive charges do. What is wrong? →
