Initialy spring in its natural length no...

Initialy spring in its natural length now a block at mass 0.25 kg is released then find out maximum force by system on floor ?

A

15 N

B

20 N

C

25 N

D

30 N

Text Solution

Verified by Experts

The correct Answer is:
C

Work - energy theory on (25) kg
`(1)/(2)Kx^(2)=mgx`
`K_(x)=2mg`
`K_(x)=2xx.25xx10`
`= 5 N`
= 25 N
`N=kx+2g`
`=5+20=25N`
