A body of mass 5 kg is suspended by a spring balance on an inclined plane as shown in figure. The spring balance measure

A

50 N

B

25 N

C

500 N

D

10 N

Text Solution

Verified by Experts

The correct Answer is:
B
Acceleration of th body down the rough inclined plane = `g sin theta`
Force applied on spring balance `= mg sin theta`
`=5 xx 10 xx sin 30^(@)=5 xx 10xx(1)/(2)=25 N`
