Question
What do you understand by normal force ?
✓

Answer

A force exerted by a surface to support the weight of a body in contact with it is called normal force. It is always perpendicular (right angles) to the surface. For example, when a book is kept on a table, the table exerts a normal force which acts upward on the book to support its weight.
