WebThe electric potential V of a point charge is given by. V = k q r ( point charge) 7.8. where k is a constant equal to 8.99 × 10 9 N · m 2 /C 2. The potential at infinity is chosen to be zero. … WebThis charge is on the surface of the sphere but it may be considered to be a point charge at its centre, as illustrated in Fig. A spark suddenly connects the metal sphere in (b) to the Earth, causing the potential of the sphere to be reduced from 7.0 × 1 0 5 V to 2.5 × 1 0 5 V. Calculate the energy dissipated in the spark.
