One-forth length of a spring of force constant K is cut away. The force constant of the remaining spring will be

A

`3/4` K

B

`4/3` K

C

K

D

4 K

Text Solution

Verified by Experts

The correct Answer is:
B
`kprop(1)/(l)`
`implies (k_1)/(k_2)=(l_(2))/(l_(1))implies (K)/(K.)=(3l//4)/(l)`
`implies K.=(4)/(3)K`.
