Question

A bucket containing water of depth 15 cm kept in a lift which is moving vertically upward with an acceleration 2g .then the pressure on the bottom of the bucket in kgwt/cm2

Answer 1

hope this will help you..::))

Answer 2

Hey dear,

◆ Answer-
P = 15 kgwt/cm^2

◆ Explaination-
# Given-
a = 2g
h = 15 cm = 0.15 m

# Solution-
Acceleration felt by bucket in a lift will be
a' = a - g
a' = 2g - g
a' = g

Pressure on the bottom of bucket due to acceleration a' is -
P = ρa'h
P = ρgh
P = 1000 × 9.8 × 0.15
P = 1470 Pa

In terms of kgwtcm^2 -
P = 15 kgwt/cm^2.

Hope it helps...
