Detailed Solution

The above statement is True.
Work done by a body depends on both the magnitude of the work done as well as the direction of the work done. A quantity having both magnitude as well as direction is called a vector quantity. The S.I unit of work is Joule. 1 Joule is the work done by an object with a force of 1 Newton with a displacement of 1 metre. As displacement is a vector quantity, work done also becomes a vector quantity.
