A conical vessel having base area 4xx10^3 m^2 and height 40 cm is filled with a liquid of density 0. 9 grarm/ cm^3 . What is the force acting on the base of the vessel due to the liquid column ? [Use g =10m//s^2 ]

Two pistons of a hydraulic machine have diameters of 30.0 cm and 2.5 cm. What is the force exerted on the larger pistion when 40 kg wt. is placed on the smaller piston? If the smaller pistion moves in through 6 cm, how much does the other pistion move out ?

A straight wire carries a current of 10A. An electron moving at 10^(3) m/s is at distance 2.0 cm from the wire. Find the force acting on the electron if its velocity is directed toward the wire?
