Question

to produce same acceleration in the bodies of masses 10 kg and 20 kg force applied on the second body should be
* halved
*double
* equal to that on first
* three times​

Answer 1

Answer:

Halved

Explanation:

Answer 2

Given:

Mass 10 kg and 20 kg has same acceleration?

To find:

Relation of force of the bodies?

Calculation:

Since acceleration of both masses are same, we can say:

$\therefore a_{1} = a_{2}$

$\implies \dfrac{F_{1}}{m_{1}} = \dfrac{F_{2}}{m_{2}}$

$\implies \dfrac{F_{1}}{10} = \dfrac{F_{2}}{20}$

$\implies F_{1} = \dfrac{F_{2}}{2}$

$\implies F_{2} = 2F_{1}$

So , 2nd body must have TWICE force as that of 1st body.
