Two metallic spehres each of mass `M` and radius `R` charged separately to `Q_(1)` and `Q_(2)` are at a distance `d` between their centres `(d gt2R)` The force between them will be

Options

A. `(1)/(4piepsilon_(0))(Q_(1)Q_(2))/(d^(2))`
B. `gt` `(1)/(4piepsilon_(0))(Q_(1)Q_(2))/(d^(2))`
C. `lt` `(1)/(4piepsilon_(0))(Q_(1)Q_(2))/(d^(2))`
D. zero

Answer

C

Explanation

Due to induction the charge distribution will be shown

the distance between the centres of changes will be gtd` rArr ` the force between them will be less than
`(1)/(4piepsilon_(0))(Q_(1)Q_(2))/(d^(2))`
