Statement-I: Minimum number of non-equal vectors in a plane required to give zero resultant is three.
Statement-II: If

\vec{a}+\vec{b}+\vec{c}=0

, then they must lie in one plane

View answer and explanation

Correct option: A

Statement-I is true and statement-II is true

Option A (Statement-I is true and statement-II is true) is correct because at least three non-equal vectors in a plane are needed for a zero resultant, and if the sum of three vectors is zero, they must lie in one plane.
