Question
List all the forces acting on the block B in figure.
Advertisements
Solution
Forces Acting on Block B:
- Gravitational force (Weight of block B) acting downwards due to Earth.
- Normal force exerted by the ground on block B acting upwards.
- Contact force from block A on block B: This will be a horizontal force acting to the right (since block A is being pushed by the man and presses against block B).
- Frictional force (if there is friction with the ground): Acts to the left, opposing motion (assuming block B tries to move right).
