a) Two objects attract each other with a gravitational force of magnitude 9.30 x109 N when separated by 19.4 cm. If the total mass of the objects is 5.06 kg, what is the mass of each?
Heavier mass_______kg
Lighter mass______ kg
my attempt:
F=Gm1m2/r^2
so I rearranged to get m1 and m2 by itself and got (r^2)(F)/G=m1m2
5.247598=m1m2
but how do I get the mass for m1 and m2 separately is m1 + m2 = 5.06 kg?
b) A dental bracket exerts a horizontal force of 86.2 N on a tooth at point B in the figure. What is the torque on the root of the tooth about point A? (PLEASE SEE THE ATTACHMENT FOR THE PICTURE)
I know I need to break the forces up into components but I am lost on this question. Please help me! Thank you
