Question : 78 of 100

Marks: +1, -0

Calculate the acceleration produced when a force of

100 {N}

is applied to an object of mass

50 {kg}

.

$0.2 {ms}^{2}$
$0.2 {ms}^{-2}$
$2 {ms}^{-2}$
$2 {ms}^{2}$

Solution:

We know that according to Newton's 2 nd law, Force

=

Mass

{x}

Acceleration
or

{F} {=}↖{→} {m} × {a}^{→}

Here,

F=100 N

and Mass

=5 0 Kg

So,

100=50 x

a

⇒ a=100 {/} 50=2

Hence, the acceleration will be

2 {ms}^{-2}

.
