The radius of gyration of a body about an axis at a distance of 6 cm from the centre of gravity is 10 cm. Its radius of gyration about a parallel axis through centre of gravity is

A

4 cm

B

14 cm

C

8 cm

D

16 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`K_(c )^(2) = K_(0)^(2)-h^(2)`
`= 100 - 36`
`K_(c )= sqrt(64) = 8 cm`.
