A 1 kg object is located at a distance of 1.7 x 10^6 m fom center of a larger object whose mass is 7.4 x 10^22 kg.
a. What is the size of the force acting on the smalle object?
b. What is the size of the force acting on the larger object?
c. What is the acceleration of the smaller object when it is released?
d. What is the acceleration of the larger object when it is released?
I need help in solving the problems.

a,b the forces are the same (GM1M2/distance^2)
c. a=F/m
d. a=F/M 
can you show me the math for a and b because I keep getting the answer 2.90 N.
