Question

giri opens a nut by applying a force of 150N using a wrench of
length 30 cm. If she wants to open it by a force of 50N, what should
be the length of the wrench?
​

Answer 1

Answer:

90 cm

Explanation:

the torque produced by the applied force remains constant in both situations

30*150=50*l

l=90cm

Answer 2

Answer:

here's your answer buddy

Explanation:

Here,

150 N force is applied with 30 cm wrench

Now,

as or,150N×30cm = 50N × 'x'

or,4500 N/cm = 50 N × 'x

4500 N/cm

or, 'x' = _4_5_0_0_N_/_cm_

50 N

or,'x'=90 cm

°•°So, we use a wrench by applying force of 50 N using a wrench of 90 cm.
