Two steel balls A and B are placed inside a right circular cylinder of diameter 54 cm making contancts at point P,Q and R as shown. The radius `r_(A)=12` cm and `r_(B)=18` cm The masses are `m_(A)=15` kg and `m_(B)=60` kg The forces exerted by the floor at the point Q and the wall at R are respectively (taking `g=10m//s^(2))`

A

`600 N, 150 N`

B

`750 N, 150 N`

C

`600 N, 200 N`

D

`750N, 200 N`

Text Solution

Verified by Experts

The correct Answer is:
D
F.B.D

`N_(V)=` vertical component
`N_(V)=m_(A)g=150N`
`N_(Q)=150+600=750N`
