1.	Two objects of masses 4kg and 3kg are placed along X and Y axes respectively at a distance of 1m from the origin. An object of mass 1kg is kept at the origin of the co-ordinate system Calculate the resultant gravitational force attraction on the object at the origin.
Answer» Solution :Force due to 4kg MASS on 1kg mass at the ORIGIN is `F_(1)= (Gxx4xx1)/1^2 = 4G` Foce due to 3kg mass on 1kg `F_(2) = (Gxx3xx1)/1^2 =3G` The resultant force is found by using parallel -gram law of vectors `F = SQRT(F_1^2+F_2^2+2F_1F_2cos THETA)` `sqrt((4G)^2+(3G)^(2)+2(4G)(3G)COS 90^@)= 5G`
