Question

The sphere of mass 1000kg are having distance of 0.5 between centres . The force of gravitational is ?​

Answer 1

Given :

$\tt \ mass_1 \: = mass_2 = 1000kg$

$\tt \: distance = 0.5m$

To Find :

$\tt \: gravitational \: force$

Solution :

$\tt\:F = GM/d²$

• Here G is the Gravitational constant whose value is 6.67 × 10-¹¹

★ According to question :-

$\tt\implies \: f = GMm/d²$

$\tt\implies \: f \: = (6.67 \times {10}^{ - 11} \times 1000) \div {(0.5)}^{2}$

$\tt\implies \: f = (6.67 \times {10}^{ - 11} \times {10}^{6} ) \div \: 0.25$

$\tt\implies \: f \: = (6.67 \times {10}^{( - 11 + 6)} ) \div 0.25$

$\tt\implies \: f \: = 6.67 \times {10}^{ - 5} \div 0.25$

$\tt\implies \: 2.67 \times {10}^{ - 5}$

∴ The answer is 2.67 × 10–5 ...

$\small{\underline{\boxed{\tt{\green{f = 2.67 \times {10}^{ - 5}}} }}}$
