Four metal conductors having different shapes a sphere, cylindrical, pear, lightning conductor are mounted on insulating stands and charge(d) The one which is best suited to retain the charges for a longer time is
- A 1
- B 2
- C 3
- D 4
Answer & Solution
Correct Answer
(A) 1
Step-by-step Solution
Detailed explanation
In case of spherical metal conductor, the charges quickly spread over its entire surface uniformly because of which charges can stay for longer time on spherical conductor. While in case of non-spherical surfaces, charge concentration is different at different points due to…
