Question

9.
Ifm1= 2 kg and m2 = 4 kg and the distance between them is 2 x 10-6m, then the force between
two masses is
N2 x 10-6m
a) 13.4 N
b) 1.334 N
C) ON
d) 1334N​

Answer 1

Answer:

use the formula

Explanation:

$f = G \frac{m1m2}{ {r}^{2} } \\ = 6.67 \times {10}^{ - 11} \frac{N {m}^{2} }{kg} \times \frac{2kg \times 4kg}{ {(2 \times { 10}^{ - 6} )}^{2} } \\ = 6.67 \times {10}^{ - 11} \frac{N {m}^{2} }{kg} \times \frac{ 2 {kg}^{2} }{ {10 }^{ - 12} } \\ = 13.34 \times 10 \\ = 133.4$
