Question

An L shaped glass tube is kept inside a bus that is moving with constant acceleration. During the motion, the level of the liquid in the left arm is at 12 cm whereas in the right arm, it is at 8 cm when the orientation of the tube is as shown in the figure. Assuming that the diameter of the tube is much smaller than levels of the liquid and neglecting effect of surface tension, acceleration of the bus will be (g = 10 m/s2).

Options

A.1 m/s2
B.2 m/s2
C.4 m/s2
D.5 m/s2

Solution

tan θ =
⇒  a = 2 m/s2
