Question

A boy opens a nut by applying a force of 200 N using a wrench of length 10 cm. If he wants to open it by a force of 50 N, what should be the length of wrench?

Answer 1

Answer:

Given

F1 = 150N

l1 = 0.4m

F2 = 60N

l2 = ?

Since, Force x perpendicular distance = constant

F1 x l1 = F2 x l2

150 x 0.4 = 60 x l2

l2 = 1 m

Explanation:

I hope it will helpful to you and plss thankful to me plzzzz

Answer 2

Answer:

Given

F1 = 150N

l1 = 0.4m

F2 = 60N

l2 = ?

Since, Force x perpendicular distance = constant

F1 x l1 = F2 x l2

150 x 0.4 = 60 x l2

l2 = 1 m
