A nut is placed in a nut cracker at 5 cm from the fixed end. If the force experienced by the nut is 100 N when a force of 20 N is applied at the free end of the nut cracker, find the length of the nut cracker.

A

5

B

25

C

15

D

20

Text Solution

Verified by Experts

The correct Answer is:
B
Mechanical advantage `=("Load")/("Effort")=("Effort arm")/("Load arm")`
Therefore, `(100)/(20)=("Effort arm")/(5)`
`implies` Effort arm =25 cm
Hence, the correct options is (b).
