Question

If a body is in equilibrium under a set of non-collinear forces, then the minimum number of forces has to be

Answer 1

Answer:

THREE

Explanation:

If a body is in equilibrium under a set of non-collinear forces, then the minimum number of forces has to be THREE

collinear force :The forces whose line of action lie on the same line,

Non -collinear force :The forces whose line of action does not lie on the same line,

For Two Forces to be in equilibrium , they must be opposite in direction & Equal in magnitude  ( Hence they would be co linear)  ( at 180 ° angle)

so Minimum three Non -collinear force Forces are required

Answer 2

right answer is three(3)
