In a hydraulic press, a `10^(7)` dyn force is applied on water by a piston of area `100cm^(2)`. If the other piston can raise a car of mass 2000 kg, then find its base area.
Text Solution
Verified by Experts
We know that, `F_(1)/alpha=F_(2)/beta` Here, `F_(1)=10^(7)dyn, alpha=100cm^(2)`, `F_(2)=2000kgxxg=2000xx1000xx980dyn` `therefore" "beta=(F_(2)alpha)/F_(1)=(2000xx1000xx980xx100)/10^(7)=19600cm^(2)`.
