Question

A force produces an accleratio of 5 cm-2
When it acts on a body of mass 2og. The force is
​

Answer 1

Answer:

The force is 10⁻³N.

Explanation:

_____________________

Given:

• Mass (m) = 20 g = 20/1000 kg
• Acceleration (a) = 5 cm/s⁻²= 5 × 10⁻²ms²

__________________________

To find:

Force.

_________________________

Solution:

We know that,

F = ma

(Where F is Force, m is mass and a is acceleration.)

F = 20/1000 × 5 × 10⁻²

= 10⁻³N

Hence,10⁻³ N is the is the required answer.

Answer 2

Given,

$a=5cm/s2$

$m=20g$

$a=5cm/s2$

$Force, F=ma$

$\: f \: = \frac{20}{1000} ×5×10 \: −2$

$F=10−3N$
