An oil tanker partially filled with oil moves forward on a level road with uniform acceleration. The free surface of oil then:
✓ Correct answer: c) is inclined to the horizontal with larger depth at the rear end
ExplanationWhen the oil tanker accelerates forward, the oil inside experiences an inertial force (pseudo force) acting in the opposite direction to the acceleration.This causes the free surface of the oil to tilt.1. The rear end of the tanker has larger depth because the inertial force pushes the oil backward.2. The front end has smaller depth as the oil moves away from it.Thus, The free surface of the oil becomes inclined, with the rear end having a larger depth 223
