Electrostatics Question 212
Question: A charge of Q coulomb is placed on a solid piece of metal of irregular shape. The charge will distribute itself [MP PMT 1991]
Options:
A) Uniformly in the metal object
B) Uniformly on the surface of the object
C) Such that the potential energy of the system is minimized
D) Such that the total heat loss is minimized
Show Answer
Answer:
Correct Answer: C
Solution:
Potential energy depends upon the charge at peaks of irregularities. Since every event in the universe leads to the minimization of energy.
