Question

what is the angle between two vectors if their scalar product is equal to the vector product

Answer 1

The scalers are those physical quantities which have magnitude only but no directions. Example- length, mass, time, temperature

Answer 2

Hello Friend!

Like all problems in physics, we start by expressing what is given:

Scalar product of two vectors= magnitude of vector product of same two vectors

Next introduce symbols, let the two vectors be a and b ,and let 0 be the angle between them(Place the two vectors in the cordinate plane, with their initial point at origin, the 0 is defined to be the smaller angle between them).

Next we use the formula, as scalar product of two vectors is defined as (ab cos0) where a and b are magnitude of vectors a and b ,

And as magnitude of vector product for two vectors is defined to be (ab sin0) where a and b are magnitude of vectors a and b ,

So we have,

ab cos 0= ab sin 0

Assume a and b not equal to 0,and cos 0 also not equal zero,

Then divide (ab cos0) to get:

tan 0=1

Or 0=pi/4

HOPE IT HELPS!
