Question

Find the gravitational force of attraction btween two spheres each of mass 1000kg the distance between the centres of the sphere is 0.5m

Answer 1

Answer:

= 2.67 × 10-4 N

Explanation:

Solution:        Mass = m1 = m2 = 1000 kg

Distance between the centers = d = 0.5 m

Gravitational constant = G = 6.673 × 10-11 Nm2kg-2

                               Gravitational force = F = ?

F = Gm1m2/d2

                                           F = 6.673 * (10)-11 * 1000*1000/(0.5)2

                                              = 6.673 * (10)-11 * (10)6 /0.25

= 6.673 * (10)-5 /0.25

= 26.692 * (10)-5

= 2.67 × 10-4 N

Answer 2

Given:

Mass 1, $m_{1}$ = 1000 kg

Mass 2, $m_{2}$ = 1000 kg

Distance between the spheres, r = 0.5 metres

To Find: Gravitational force of attraction

Calculation:

• Gravitational force is the force of attraction between two bodies.
• Force of gravitation is inversely proportional to the square of distance between the bodies and directly proportional to the multiplication of masses of two bodies.

It is given as:

$F = G*\frac{m_{1} m_{2} }{r^{2} }$

$F=6.67*10^{-11} *\frac{1000*1000}{0.5*0.5}$

$F=26.68 *10^{-5} N$

Answer:

Gravitational force of attraction between two spheres is $26.68*10^{-5}$Newton.
