Question

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

Answer 1

m1= 10 kg ; m2= 20 kg

r= 100 m and G=1.6×10^-11Nm^2/kg^2

We know that,

F=G m1m2/r^2

F=1.6×10^-11×10×20/100×100

F=0.032×10^-11 N

Plz mark as the brainliest answer.

Answer 2

$\huge{\underline{\underline{\red{\mathfrak{Answer :}}}}}$

$\tt Given \begin{cases} \sf{Mass \: of \: 1st \: Sphere \: (m_1) \: = \: 10 \: kg} \\ \sf{Mass \: of \: 2nd \: Sphere \: (m_2) \: = \: 20 \: kg} \\ \sf{Distance \: (d) \: = \: 100} \end{cases}$

♣ We have to find value of g

We have formula for gravitational force :

$\huge{\underline{\boxed{\tt{g \: = \: G \: \dfrac{(m_1)(m_2)}{d^2}}}}}$

Where Value of G is 6.67 * 10^-11

Put Values

⇒g = 6.67 * 10^-11 * 10 * 20/(100)²

⇒g = 6.67 * 10^-11 * 200/10000

⇒g = 1.34 * 10^-12 N

$\large{\boxed{\sf{g \: = \: 1.34 \: \times \: 10^{-11}}}}$

∴ Gravitational Force between them is 1.34 * 10^-12 N
