Question
There are two thin films, A of liquid and B of polythene, identical in size. They are being pulled with same maximum weight W. If the breadth of the films is increased from b to 2b then the corresponding weights will be respectively -
Options
A.W, W
B.
C.
, W
, WD.W,
Solution
Potential energy
= mg
(rh)2
according to Zurin law rH = constant ⇒ u1 = u2
= mg
(rh)2according to Zurin law rH = constant ⇒ u1 = u2
