A water tanker filled up to $\frac{2}{3}$ of its height is moving with a uniform speed. On sudden application of the brake, the water in the tank would
$(a)$. move backward
$(b)$. move forward
$(c)$. be unaffected
$(d)$. rise upwards

AcademicPhysicsNCERTClass 9

When a water tanker filled up to two-thirds of its tank with water is running at a uniform speed. When the brakes are suddenly applied, the water in its tank would move forward due to inertia of motion. Although, the tank has been stooped by applying brakes the water in its tank tends to remain in the state of motion.

So, option (b) is correct.
