Two large parallel metal plates are 2.2 cm apart and have charges of equal magnitude but opposite signs on their facing surfaces. Take the potential of the negative plate to be zero. If the potenti
After the collision the two pucks fly apart, puck A deflects above the x-axis at a 65-degree angle, puck B deflects below the x-axis at a 37-degree angle. Find the final speed of (a) puck A and (b)
If you move along an equipotential line, no work is done since the potential difference is zero along the line. With this, explain why electric field lines must be at right angles to equipotential
