Question

a force of 5N acts on a body of weight 9.8 N. what is the acceleration?
​

Answer 1

Answer:

weight is 9.8N hence the mass is 1 kg....then the acceleration will be 5/1=5 m/s²

Answer 2

Answer:-

The acceleration of the body is 5m/s²

Step-by-step explanation:-

Given that,

Force = 5 N and Weight = 9.8 N

Therefore,

$\sf{ Weight(W)= mg}$

So,

$\sf{Mass= \dfrac{W}{g} }$

$\sf{Mass = \dfrac{9.8}{9.8}}$

Dividing 9.8 and 9.8 with 9.8

$\tt{ \therefore \: Mass = 1kg}$

Now, Let's find Acceleration ( a )

We know that,

$\sf{ Force= ma}$

Therefore,

$\sf{Acceleration(a) = \dfrac{F}{m} }$

$\longrightarrow \: a = \dfrac{5}{1}$

$\longrightarrow \: 5 {m/s}^{2}$

$\tt{ \therefore \: Acceleration = 5 {m/s}^{2} }$

Required Answer:-

Acceleration of the body is 5m/s².

Remember:-

• 1 N = 1 kg m s-²
• 1 kgf = 9.8 N ( approximately taken as 10 N )
• The CGS unit of force is dyne.
