Question

Twe spheres of masses 64 kg and 298 kg
are placed at a distance of 10 cm apart.
Find the position of the point on the line
joining the centre of the two spheres,
where the gravitational field is zero.

Answer 1

Twe spheres of masses 64 kg and 298 kg

are placed at a distance of 10 cm apart.

Find the position of the point on the line

joining the centre of the two spheres,

where the gravitational field is zero.

Answer 2

Answer:

6.83 CM

let that point be x from smaller sphere along the axis . remaining distance is 10 - x.

the Pulls of each ball at the point must Counteract equally on a Unit mass placed here

we get

64/ x^2= 298/ (10-x)^2

or

10-x/ x = root( 64/298) = 0.463

10/x= 1.463

x = 10/1.463

6.83 can from smaller sphere toward Bigger sphere.
