hi i have some questions about Newtons law of gravitation and i need complete answers coz these qwestion will be my second exam: 1.the gravitational force between a ring of raduis a and mass m and a rod of mass m and length l lies on the central axis of the ring and the distance is x between...

thank you so much wish me luck in my exam tommorow

and by the way am a girl

i just got hint from my teacher that i should use the double integral

we should use the integral for both as we did with a point mass and uniform rod..the two rods lying on the x-axis with separation a ___ ___ they are equal in mass and length

:smile:hi i need to know how can we find the gravitational force between two uniform rods of mass m and length l?
