Question

what is the property of vector p and vector Q is vector P + vector Q is equal to vector P - vector q
options.....
1 p is null vector
2 Q is null vector
3 p is proper vector
4 Q is proper vector

Answer 1

p vector + q vector= p vector - q vector

or...
q vector = - q vector
or...
2q vector=0
or..
qvector=0

So q vector is null vector.
