Question

When is resultant of three vectors is zero?

Answer 1

$\textbf{Answer}$

Resultant of three vectors will be zero if all of the following conditions are applicable -

● Three vectors are coplanar which means all three vectors are in the same plane.

● All three vectors form a triangle together which means they form three sides and three angles and three vertices.

● If magnitude of resultant of two vectors is exactly equal to the magnitude of the third vector.

● If direction of resultant of those two vectors is exactly opposite to the direction of the third vector.

If all above conditions are satisfied, then the resultant of three vectors will be zero.
