Question

Study the given diagram and find the gravitational force between two spherical objects.(ans:3.335×10-⁷N)​

Answer 1

3.335

Explanation:

$f = \frac{km1m2}{ {r}^{2} }$

$f = \frac{6.67 \times {10}^{ - 11} \times 800 \times 400}{( {6 + 2)}^{2} } \\ f = \frac{6.67 \times {10}^{ - 11} \times 320000} {64} \\ f = \frac{6.67 \times {10}^{ - 11} \times 10000}{2} \\ f = 6.67 \times {10}^{ - 11} \times 5000 \\ f = 3.335\times {10}^{ - 7}$

where G(k) Is gravitational constant
