$\huge\mathcal{Anyone pls answer to the question in the attachment....!!!!}$​

Answer 1

this is one of the difficult sum in ncert 11th

but if you try to solve it will be more easier.

just refer the below answer.

your answer is hear my friend...

6.67 × 10^ -⁸

given -

G= 6.67 × 10^ -¹¹

We know that,

1N = 1kg m s-2

1 kg = 103 g

1m = 100cm= 102 cm

Put the values together, we get:

6.67 x 10-11 Nm2 kg-2

= 6.67 x 10-11 x (1kg m s -2) (1m2) (1kg-2)

Solve the following and cancelling out the units, we get:

= 6.67 x 10-11 x (1kg -1 x 1m3 x 1s-2)

Put the above values together to convert kg to g and m to cm

= 6.67 x 10-11 x (103g)-1 x (102 cm)3 x (1s-2)

= 6.67 x 10-8 cm3 s-2 g -1

Then,

G = 6.67 x 10-11 Nm2(kg)-2

= 6.67 x 10-8 (cm)3 s-2 g -1

hope this will help you....
