Question

25)Two forces are acting on a block in opposite directions as shown in the figure above

(a) Calculate the net force acting on the block.
(b) In which direction will the net force tend to move the object?
(c) Will any other force try to oppose the motion of the block? ​

Answer 1

`\boxed{ \sf{Answer}}`

____________________

(a) A = 5 kgwt

B = 10 N

First convert 5 kgwt to N,

`5 * 9.8 \\ = 49 \: N`

Net force [the forces are acting in 2 opposite directions]

`A - B \: \\ = 49 - 10 \\ = 39 \: N`

____________________

(b) Since, the force is greater by A ↦the block will move towards B, i.e, to the right.

____________________

(c) Frictional force will try to oppose the motion of the block but since A has greater force than B, the frictional force will be resisted.
