Question

2. The masses of two spheres are 10 kg and 20 kg respectively. If the
distance between their centres is 100 m, find the magnitude of
the gravitational force between them.​

Answer 1

Answer:

$f = 1.334 \times {10}^{ - 16} n$

f stands for force of gravitation

Step-by-step explanation:

Let

• M = 20 kg
• m = 10 kg
• d = 100 m
• g is the universal constant of gravitation

$g = 6.67 \times {10}^{ - 11}$

According to the Newton's universal law of gravitation

$f = \frac{gmm}{ {d}^{?} }$

Therefore, by substituting values

$f = \frac{6.67 \times {10}^{ - 11} \times 10 \times 20}{ {100}^{2} } \\ f = 1334 \times {10 }^{ - 13} \\ f = 1.334 \times {10}^{ - 16} newtons \:$

And:-

The magnitude of the gravitational force between them is as above.
