How Strong is the Gravitational Pull Between Two Students?

AI Thread Summary
The gravitational attraction between two students with masses of 70 kg and 50 kg, separated by 1.5 m, can be calculated using the formula Fg = Gm1m2/r^2. The gravitational constant G is approximately 6.67 x 10^-11 N(m/kg)^2. When the values are plugged into the equation, the resulting force is expected to be very small due to the relatively low masses and the distance involved. The radius of 1.5 m is correctly used in the calculation. Overall, the gravitational pull between the two students is negligible.

Homework Statement


what is the gravitational attraction between two students with masses of 70 kg and 50 kg, if they are 1.5 m apart?

Homework Equations


Fg=Gm1m2/r^2


The Attempt at a Solution


so my Fg is 6.67 x 10^-11, m1 is 70 kg and m2 is 50 kg. for my radius, do i just use the 1.5 m and plug it into the formula? or no i need to do something else?

that sounds correct. The force should be very small.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
