Question

The component of a along b is root 3 times that of the component of b along a. Then, is a : b?

Answer 1

`√(3) :1`

Explanation:

Given:

`\vec{a}_{\vec{b}}=√(3)* \vec{b}_{\vec{a}}`

`|\vec{a}|cos\theta=√(3) *|\vec{b}|cos\theta`

`|\vec{a}|=√(3) *|\vec{b}|`

`|\vec{a}|:|\vec{b}|=√(3) : 1`
