A 19 kg sphere is at the origin and a 12 kg sphere is at (x,y)=( 18 cm , 0 cm) . At what point or points could you place a small mass such that the net gravitational force on it due to the spheres is zero? Express your answers using two significant figures separated by a comma.
Let x be the position of the mass from the origin.
Then, the net gravitational field strength on it will be:
=>
12x2 = 0.6156 - 6.84x + 19x2
=> 7x2 - 6.84x + 0.6156 = 0
solving this gives x = 0.8768 m and x = 0.1003 m
since x = 0.8768 m will be to the right of both the spheres, it will be unstable and so it must be discarded.
Therefore, x = 0.1003 m = 10.03 cm is where the small mass must be for the net gravitational force to be zero on it.
