Question

Please give correct answer​

Answer 1

The force applied is F=10 N

The displacement occur is s=30 cm

Convert cm into m,

1 cm = 0.01 m

30 cm = 0.3 m

The formula to find work done is

W=F\times sW=F×s

Substitute the value in the formula,

W=10\times 0.3W=10×0.3

W=3 JW=3J

Therefore, Work done by Ravi is 3 joules.

Hope this'll help you.

Answer 2

Ans is 3 Nm.

we have to first convert cm into metres
