Questions
20 N force is applied to the massless piston of area A1 as shown. What force F must be applied to massless piston of area A2 if the level of water in both the tubes is at the same horizontal level.
detailed solution
Correct option is B
Given Applied force F=20 N Area of Piston=A1 Area of Piston=A2 Applying Pascal's law F1A1=F2A2 ⇒20cos60A1=FA2 ⇒102=F20 ⇒F=100 NTalk to our academic expert!
