Question

physics

If the a component of a vector A, in the ry plane, is half as large as the magnitude of the vector, the tangent of the angle between the vector and the r axis is:​

Answer 1

Answer:

Suppose,the a vector makes an angle θ w.r.t the X axis,

so,its X component becomes acosθ

Now,given, acosθ=a2

so, θ=60

tan60=√3
