## Homework Statement

Can

1. three

2. four

vectors in

**different planes**add up to give a zero resultant?

## Homework Equations

## The Attempt at a Solution

1. Yes.

2. Yes.

1. suppose that we resolve the 3 vectors in i,j,k components. Putting each one of them zero in the respective three vectors to make them in 3 separate plane. Cant they be zero?

2. similar as above. the only thing is that the fourth vector has none of its components zero.

Am I right?
