Question

The resultant of two vectors is perpendicular to one
of them and has the magnitude 4 m. If the sum of
the magnitude of two vectors is 8 m then their
respective magnitude are

(1) 4 m, 4 m
(2) 2 m, 6 m
(3) 3 m, 5 m
(4) 1 m, 7 m​

Answer 1

Explanation:

I can't help out bye next time

Answer 2

Answer:

Answer: answer is (3) i.e. 3m,5m.

Explanation:let one of the vector be a and other be b.

Now

a^2+4^2=b^2.....................(1)

And

a+b=8...................................(2)

From (1) and (2)

We get a=3 and b=5

Hope it was enough
