For the given situation shown in figure , choose the correct option `(g = 10 m//s^(-2))`

A

50

B

30

C

20

D

70

Text Solution

Verified by Experts

The correct Answer is:
A

`N_(1) sin 30^(@) = N_(2) sin 60^(@)`
`N_(1) cos 30^(@) + N_(2) cos 60^(@) = mg`
Solving above equation
`N_(2) = (mg)/(2) = (10 xx 10)/(2) = 50`
