Question

A vector has x-component 8N and y-component 6N. The magnitude of the vector is (a) 10 N (b) 14N (c) 24N (d) 5N​

Answer 1

Answer:

Let the vector be A

then,

Ax = 8

Ay = 6

Then (A = Axî + Ayĵ)

A = 8î + 6ĵ

Magnitude of A = $\sqrt{Ax^{2} + Ay^{2} }$

=>$\sqrt{8^{2} + 6^{2} }$

=>$\sqrt{64+36}$

=>$\sqrt{100}$

=>10

Option a)10N
