Physics Class 11 Chapter 6 Fluid Dynamics MCQs

MCQs are made in such a way that no important aspect is missed out. Any student taking a test and getting more than 90% marks will surely get similar marks in board exam. According to Stoke’s Law, the drag force on a body moving in fluid is directly proportional to the velocity of the body? The product of cross-sectional area of the pipe and the speed at any point along the pipe is constant? Terminal velocity of a body falling in a fluid is the minimum velocity? The speed of efflux is equal to the velocity gained by the fluid in falling through the vertical distance under the action of gravity?
