Question

answer me please.......,.....​

Answer 1

Answer:

1. SI unit of G is

$Newtons \: kg^{ - 2} m^{2}$

2. going higher will decrease g

3. Mass of a body remains same everywhere.

4. Weight is measured by spring balance.

Explanation:

Relation between g and G:

According to the universal law of gravitation,

F=GMm/R2 ————(1)

From Newton’s second law of motion we can write –

g=F/m ———–(2)

Substituting equation (1) in (2) we get-

g=GMm/R2m

Thus, we arrive at the g formula in physics as –

⇒g=GM/R2

Answer 2

Answer:

1. SI unit of G is Newton kg - ²m²

2. going higher will decrease g

3. Mass of a body remains same everywhere.

4. Weight is measured by spring balance.

Q Relation between g and G:

According to the universal law of gravitation,

F=GMm/R2 ————(1)

From Newton’s second law of motion we can write –

g=F/m ———–(2)

Substituting equation (1) in (2) we get-

g=GMm/R2m

Thus, we arrive at the g formula in physics as –

⇒g=GM/R2
