Question

The resultant of two forces \( P \) and \( Q \) (such that \( P>Q \)) acting along the same straight line, but in opposite direction, is given by:

• A. \( P + Q \)
• B. \( P - Q \)
• C. \( P/Q \)
• D. \( Q/P \)

Hint:

When two forces act along the same line but in opposite directions, the resultant is simply the difference between the larger and the smaller force, indicating the net force direction towards the larger force.

Answer 1

The Correct Option is B

Understanding the forces acting in opposite directions.
Since the forces \( P \) and \( Q \) are acting along the same line but in opposite directions, their resultant is the difference between the two because the larger force \( P \) will partly cancel out the force \( Q \).
