Two coaxial solenoids of different radii carry current I in the same direction. Let `vecF_(1)` be the magnetic force on the inner solenoid due to the outer one and `vecF_(2)` be the magnetic force on the outer solenoid due to the inner one. Then : `vecF_(1)` is radially inwards and `vecF_(2)` is radially outward

Options

A. `barF_(1)=barF_(2)=0`
B. `barF_(1)` is radially inwards and `barF_(2)` is radially outwards
C. `barF_(1)` is radially inwards and `barF_(2)=0`
D. `barF_(1)` is radially outwards are `barF_(2)=0`

Answer

1

Explanation

`vecF_(1)=vecF_(2)=0`
Because net resultant will be zero.and equal because of action and reaction pair
