In melde's experiment , 3 loops are formed of by putting a weight of 8gm in a massless pan. Then the weight required to form two loops is

A

18gm

B

8gm

C

36gm

D

24gm

Text Solution

Verified by Experts

The correct Answer is:
A
`T_1P_1^2= T_2P_2^2`
`T_2=(P_1^2)/(P_2^2) = T_1 = 9/4 xx8 = 18gm`
