Three point charges of 0.1 C each are placed at the corners of an equilateral triangle with side L =1 m. If this system is supplied energy at the rate of 1 kW, how much time will be required to move one of the charges to the midpoint of the line joining the other two?

Three equal charges q are placed at the vertices of an equilateral triangle of side a. (a) Find out potential energy of charge system. (b) calculate work required to decrease the side of triangle to a/2. (c) if the charges are released from the shown position and each of them hass same mass m, then find the speed of each particle when they lie on triangle of side 2a.

Three-point charges 1C,2C, and 3C are placed at the corners of an equilateral triangle of side 1m. The work required to move these charges to the corners of a smaller equilateral triangle of side 0.5m shown in the fig
