Question

Answer of the given question needed:

1. How much work is done when:
a) a 6N force moves 3m?
b) a 12 N force moves 0.5m?
c) a ION force moves 10mm?​

Answer 1

Answer:

a. 18 joule

b. 6 joule

c. 0.1 joule

Explanation:

We know,

Work = Force * Distance

Answer 2

$\sf{Answer}$

Solution:-

Work done :- Work done by force is measured as the product of magnitude of force & distance

Work done is scalar product

Work done SI unit is Joule

W = F.S

_______________

1 ) F = 6N

• S = 3m

Work done = F.S

Work done = 6 N × 3m

Work done = 18 J

_______________________

2)

• F = 12 N
• S = 0.5 m

W = F.S

W = 12 N × 0.5 m

W = 6 J

_______________________

3)

• F = 10 N
• S= 10mm

1mm = 10^-3 m

W = F.S

W = 10 × 10^-3

W = 10^-2 J

W = 1 /10² J

W = 1 /100 J

W = 0.01 J
