What is the magnitude of the net gravitational force on the m2=5kg mass? Assume m1=25kg and m3=15kg.
The Attempt at a Solution
First I find the angle between m1 and m2 which is arctan(10/20)=27
Find the force m3 on m2 which is
There also a force acting m2 on m1 which is
the net force, I do Fnet=sqrt((8.91*10^-9Ni)^2+(-2.09*10^-7Nj-4.54*10^-9Nj)^2)=2.137*10^-7N
However, the answer I got is incorrect.
can anyone tell me where I did wrong?
