Two coaxial solenoids of different radius carry current I in the same direction. `vec(F_1)` be the magnetic force on the inner solenoid due to the outer one and `vec(F_2)` be the magnetic force on the outer solenide due to the inner one. Then

A

`vecF_1` is radically inwards and `vecF_2 = 0 `

B

`vecF_1` is radically outwards and `vecF_2 = 0 `

C

`vecF_1 = vecF_2=0`

D

`vecF_1` is radically inwards and `vecF_2` is radically outwards

Text Solution

Verified by Experts

The correct Answer is:
C
`vecF_1 =vecF_2 = 0 `
because of action and reaction pair
