Three identical particle A, B and C of mass 100 kg each are placed in a straight line with AB = BC = 13 m.

Three identical particle A, B and C of mass 100 kg each are placed in a straight line with AB = BC = 13 m. The gravitational force on a fourth particle P of the same mass is F, when placed at a distance 13 m from the particle B on the perpendicular bisector of the line AC. The value of F will be approximately : 

A: 21 G

B: 100 G

C: 59 G

D: 42 G

Correct option is (B) 100 G
