﻿ In which of the following examples of motion, can the body be considered approximately a point object: (a) a railway carriage moving without jerks between two stations from Physics Motion in Straight Line Class 11 CBSE

In which of the following examples of motion, can the body be considered approximately a point object:

(d) a tumbling beaker that has slipped off the edge of a table.
