Two point objects of masses 1.5 g and 2.5 g respectively are at a distance of 16 cm apart, the centre of gravity is at a distance x from the object of mass 1. 5 g where x is

Answer»

10 CM
6 cm
13 cm
3 cm

Solution :
TAKING the moment of FORCES about centre of gravity G
(1.5)g `XX` = 2.5g (16-x)
`rArr3x=80-5x`
or `8x=80` or x=10 cm
