Question 15 :
State whether true or false.<br/>If a body is moving with a constant speed along a straight line, then in order to change its direction of motion, an external force or its component has to act in a direction normal to the direction of motion.

Question 16 :
A right angled tube is fixed horizontally on a horizontal surface and an ideal liquid of density p is flowing into the tube at the rate of $Q = 4 m^3/s$ Cross sectional area of the tube at intake and outlet positions are $A = 2 m^2$ and $S = 1 m^2$ respectively. The magnitude of net force exerted by liquid on the tube is (Given that the value of atmospheric pressure $P_o = 4p N/m^2$)
