Question

What is the angle between the vectors A with arrow and B with arrow if A with arrow·B with arrow = -0.707 AB?

science physics

Answer 1

Answer #1

Given:

A with arrow·B with arrow = -0.707 AB

we know that,

A with arrow·B with arrow = ABcos()

so cos()= -0.707

=cos^-1(-0.707)=135 degree
