Answer 1

Question :-

Find the net forces from the given diagrams.

Answer :-

(a) Net force :

• (8N + 10N) - (12N)
• 18N - 12N
• 6N

Therefore, net force is 6N.

(b) Net force :

• 8N - 8N
• 0N

Therefore, net force is 0N.

(c) Net force :

• 8N + 6N
• 14N

Therefore, net force is 14N.

(d) Net force :

• 9N - 8N
• 1N

Therefore, net force is 1N.

Important shots :-

• Net force is defined as the sum of all the forces acting on an object.
• Net force can be zero also.

Answer 2

Answer:

Step-by-step explanation:

fig A: Fnet = Fa + Fb + Fc

Fa=10N, Fb=8N, Fc=12N.

Fnet = 8 + 10 + (-12)     =>because Fc is in opp. direction.

Fnet = 6N, (LEFT).

similarly fig-b: Fnet is zero.

fig-C: fnet: 14N, (right)

fig-D: fnet; 1N (upward)
