Question

Two vectors A and B lie in one plane. Vector C lies in a different plane. Then A + B + c​

Answer 1

Explanation:

Since the third vector has a component which lies outside the plane of the remaining two, hence this extra component can not be cancelled by any other component during addition, so sum can never be zero.

Also, the sum lies outside the plane of

A+B

(which is the same plane as

A and B

) because of this extra component of

C

please mark my answer as brainest answer as

Answer 2

Answer:

The sum of A, B and C will never be equal to zero.

Explanation:

• It is given that the Vector C lies in a different plane.
• We know that only the components present in the same plane can be cancelled through addition or subtraction.
• Since vector c can not be cancelled, the sum of A, B, and C cannot be equal to zero.
• If the sum of A and B is zero, the resultant value will be equal to vector C.
