Question

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

Answer 1

$\boxed{ \sf{Answer}}$

____________________

(a) A = 5 kgwt

B = 10 N

First convert 5 kgwt to N,

$5 \times 9.8 \\ = 49 \: N$

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.
