Two rods A and B of the same material and length have radii `r_(1)` and `r_(2)`respective. When they are rigidly fixed at one end and twisted by the same torque applied at the other end, the ratio `[("the angle of twist at the end of A")/("the angle of twist at the end of B")]` equal to

A

`(r_(1)^(2))/( r_(2)^(2) )`

B

`(r_(1)^(3) )/( r_(2)^(3))`

C

`( r_(2)^(4) )/( r_(1)^(4) )`
