Question
CBSEENPH11017451

Find the gravitational force between two masses each of 1gm separated by a distance 1cm.

Solution

Gravitational Force,space space straight F space equals space fraction numerator Gm subscript 1 straight m subscript 2 over denominator straight r squared end fraction
Here, we have
Mass of the body, straight m subscript 1 equals straight m subscript 2 equals 1 gm comma
Radius, r = 1 cm
∴ Gravitational force,
     space space space straight F equals fraction numerator 6.67 cross times 10 to the power of negative 8 end exponent cross times 1 cross times 1 over denominator left parenthesis 1 right parenthesis squared end fraction equals 6.67 cross times 10 to the power of negative 8 end exponent dyne
