Question

Drums of oil are carried in a truck. If constant acceleration is applied on the truck the surface of the oil in the drum will
A) Remain unaffected
B) Rise towards forward direction
C)Rise towards backward direction​

Answer 1

c

Explanation:

rise in the backward direction.

Due to inertia the oil will try to retain its position hence the surface of the oil will rise in backward direction.

Answer 2

Answer:

Drums of oil exist taken in a truck. If constant acceleration exists involved in the truck the surface of the oil in the drum will rise in the backward direction.​

The correct answer is option C) Rise in the backward direction​.

Explanation:

Drums of oil exist taken in a truck. If constant acceleration exists involved in the truck the surface of the oil in the drum will rise in the backward direction.

Forces working on the surface are:

(1) mg downward

(2) pseudo force opposite to the direction of acceleration of structure of reference.

The liquid surface orients itself perpendicular to the resulting force.

So, the surface of oil will increase in the backward direction.

Therefore, the correct answer is option C) Rise in the backward direction​.
