Question

6. Maximum and minimum magnitudes of the resultant of two vectors of magnitudes P and Q are
found to be in the ratio 3:1. Which of the following relations is true ?
1) P = Q
2) P=2Q
3) P = 4Q
4) P = Q/3

Answer 1

Answer:

Two vectors of magnitudes P and Q are found to be in a ratio 3:1. The magnitude of two vectors will be maximum when they are added together and minimum they are subtract. Hence, P=2Q is correct relation.
