Exam points
- Calculate the resultant force along one line by combining collinear force magnitudes and giving the direction.
- Recognise zero resultant force when opposing forces balance, including when an object is stationary or moves at constant speed.
Edexcel IGCSE Physics 1.15 Resultant Force Questions question 1
Diagram 1 shows a wooden plank balanced horizontally on two supports, A and B.
A block is suspended from the plank between the supports by a cable of negligible weight.
Diagram 1
Diagram 2 shows the block and the cable connecting the block to the plank.
The block also experiences a force due to the tension in the cable.
Explain why the block remains stationary when it is supported by this tension force.
