Question

all numerical of gravitational chapter class 9​

Answer 1

Ｑｕｅｓｔｉｏｎ:-

Determine the gravitational force if two masses are 30kg and 50kg separated by a distance 4m.

G = 6.67259 x 10–11 N m2/kg2.

~ $\small \blue {\sf{Answer }}$✨❤

Given:

m1 = 30 kg, m2 = 50 kg

r = 4m and

G = 6.67259 x 10–11 N m2/kg2.

Universal gravitation formula is given by,

Universal Gravitation Formula

= [6.673×10–11 ×30×50] / 16

F = 62.55 x 10–11N

Ｑｕｅｓｔｉｏｎ:-

Determine the gravitational force if the mass of two bodies are 80 kg and 200 kg and they are separated by a distance of 6m.

~ $\small \blue {\sf{Answer }}$✨❤

Given:

m1 = 80 kg, m2 = 100 kg,

r = 6m and

G = 6.67259 x 10–11 N m2/kg2.

Universal gravitation formula is given by,

F=Gm1m2 / r2

=6.673×10–11× 80×100 / 36
