Question

A force produces an acceleration of 6cm/sec2 in a body of mass         40grams. Then find out the force acting on the body in newton.​

Answer 1

• Mass=40g=0.04kg
• Acceleration=6cm/s^2=0.06m/s^2

Using Newton's second law

$\boxed{\sf Force=Mass\times Acceleration}$

$\\ \sf\longmapsto Force=0.04\times 0.06$

$\\ \sf\longmapsto Force=0.0024N$

Answer 2

Answer:

Provided that:

• Acceleration = 6 cm/s sq.
• Mass = 40 g

To calculate:

• Force

Solution:

• Force = 0.0024 N

Knowledge required:

• SI unit of force = N
• SI unit of mass = kg
• SI unit of acceleration = m/s²

Using concepts:

• Force formula
• Formula to convert cm into m
• Formula to convert g into kg

Using formulas:

• F = ma
• 1 cm = 1/100 m
• 1 g = 1/1000 kg

Required solution:

~ Firstly let us convert g into kg!

→ 1 g = 1/1000 kg

→ 40 g = 40/1000 kg

→ 40 g = 4/100 kg

→ 40 g = 0.04 kg

• Therefore, converted!

~ Now let us convert cm into m!

→ 1 cm = 1/100 m

→ 1 cm = 6/100 m

→ 1 cm = 0.06 m

• Therefore, converted!

Henceforth,

• Mass = 0.04 kg
• Acceleration = 0.06 m/s²

~ Now let's find force!

→ F = ma

→ F = 0.04(0.06)

→ F = 0.0024 N

• Therefore, solved!

Henceforth, force = 0.0024 N
