Two point masses each equal to 1 kg attract one another with a force of `9.8 ×10^(-9)` kg-wt. the distance between the two point masses is approximately `(G = 6.6 xx 10^(-11) "MKS units")`

A

8.2 cm

B

0.8 cm

C

82 cm

D

0.08 cm

Text Solution

Verified by Experts

The correct Answer is:
A
`F=(Gm_(1)m_(2))/(r^(2)`
`therefore r=sqrt(Gm_(1)m_(2))/(F)=sqrt(6.67xx10^(-11)xx1xx1)/(9.8xx10^(-9))`
`=0.082 m =8.2 cm`
