Question

A man in a lift holds a bucket of water with a small hole at the bottom. If the flow rate is R₀ in a stationary lift, Rᵤ when lift accelerates upward and Rdown when it accelerates downward with the same magnitude, then:

Options

G1 Physics · Accepted Answer

Efflux speed varies as √(effective g). Upward acceleration gives effective g=g+a; downward gives g-a. Thus Rᵤ>R₀>Rdown. Option B.
