Question

calculate the mass of body weighing 100dyne take g=10 m/s²

Answer 1

Weigth= mg

But as weight is in dyne converting it in SI unit Newtons;

1dyne=10^-5Newtons

So,

100×10^-5÷9.8=mass of the body

So mass =10.24×10^-5kg

Answer 2

The mass of body weighing 100 dyne take g=10 m/s² is $10.24 \times 10^-5$ kg.

Explanation:

In the above given question we are provided with the weight or mass of a body but the unit of expressing this weight is given in dynes.

Now in this question we have to convert this weight into kilograms.

We know that weight is mass times Gravity and here as in the question we have to calculate using gravity as 9.8 meter per second square.

1 dyne is equivalent to $10^-5$N

Now applying this value to 100 dynes.

We get $= 100 \times 10^{\frac{-5}{9.8}}$

= $10.24 \times 10^{-5} kg$
