Which one of the following vector equations is wrong ?

Options

A. `vec P + vec Q = vec R`
B. `vec P - vec Q = vec R`
C. `vec P + Q= vec R`
D. `vec P = vec R - vec Q`

C

Explanation

Equation `vec P + Q =vec R` is wrong because we cannot add vector `vec P` and a scalar Q We can multiply or divide `vec P` by Q.
