Question

Two forces 3N and 4N acting on an object what can be maximum and minimum resultant forces on object?

Answer 1

By “magnitude”, you’re asking for the “scaler” and not the “vector” so that’s just √ (3^2 + 4^2). It’s just Pythagorean. (You can finish that on your calculator).

Answer 2

maximum can be 7N (if acting in the same direction)

minimum can be 1N (if acting in opposite directions)
