Question

twobodies of masses 4 kilograms and 36 kilograms are at the distance 0.5 m apart .At which point on the line joining them a mass of 1 km experiences the net gravitational force 0​

Answer 1

Answer:

11x=1

Explanation:

Let the resultant gravitational intensity be zero at distance x from the mass of 10 kg on the line joining the centres of the two bodies. At this point, the gravitational intensities due to the two bodies must be equal and opposite.

∴

x

2

Gx10

=

(1−x

2

)

2

Gx1000

or 100x

2

=(1−x)

2

or 10x = 1 - x

or 11x = 1 or x = 1/11 m.
