Answer:
26 N
Explanation:
First, see the attachment properly and know all the points and see my solution, it will be really helpful.
Given:-
Weight of spherical Ball= 50 N
Radius of the ball= 20 cm
Solution:-
From Fig,
CF=BE=h=5 cm
Radius= OB=OF=20 cm
OC=OF-CF
OC=20-5
OC=15 cm
From that,
DC=OD+OC
DC=10+15
DC=25 cm
DC=AB=25 cm
From Right angled triangle OBC,
By Pythagoras Theorem,
By condition of equilibrium,we have,
∑T=0 (Pivot point is B)
F(AB)-W(BC)=0
F(25)-50(13.2)=0
25F-660=0
25F=660
F=26.4 N
F=26 N
Hope it helps you!
