Question

Two bodies of mass 5kg and 15kg are separated by a distance of 5m. Calculate the gravitational force

between them.​

Answer 1

Answer:

F = Gm1m2/r^2

G= 6.7×10^-11

F= (6.7×10^-11×5×15)/5×5

F= 2×10^-10 N

Answer 2

Step-by-step explanation:

$Let \: the \: gravitational \: field </p><p></p><p>$

$is \: zero \: at \: a \: distance \:  x$

$from \: 5 kg \: mass \: and \:$

$distance  \: (5−x) from \: 15kg \: mass. </p><p></p><p>$

$Thus,   \frac{gm1}{ {x}^{2} } = \frac{gm2}{ {(5 - x)}^{2} } </p><p>$

$or  {3x}^{2} =({15} - x)^{2} </p><p> </p><p>or 3x=15−x </p><p></p><p>or x=5m$

$Thus, \: field \: is \: zero \: at \: 5 m$
