प्रश्न
In the following example of motion, can the body be considered approximately a point object:
A tumbling beaker that has slipped off the edge of a table.
उत्तर
The size of the beaker is comparable to the height of the table from which it has slipped. Therefore, the beaker cannot be considered a point object.
