Question

Please solve q 28?

Answer 1

40 N

Explanation:

Since the two components - lets call them `P` and `Q` - are mutually perpendicular, their resultant is given by

`sqrt(P^2+Q^2)`

So

`50" N" = sqrt((30" N")^2+Q^2) implies`

`Q^2 = (50" N")^2-(30" N")^2 = 1600" N"^2 implies`

`Q = 40" N"`
