AI Thread Summary
The discussion focuses on calculating the forces between two protons separated by 4.0 femtometers. The electric force between the protons is calculated to be 14 N using the formula F = Kq1q2/r^2. Participants are seeking guidance on how to calculate the gravitational force between the protons. The gravitational force is significantly weaker than the electric force, and users are encouraged to refer to resources for gravitational calculations. The final goal is to determine the ratio of the electric force to the gravitational force.

Homework Statement



Two protons are 4.0 fm apart. ( 1 fm= 1 femtometer = 1*10^-15m)
a)What is the magnitude of the electric force on one proton due to the other proton?
b)What is the magnitude of the gravitational force on one proton due to the other proton?
c)What is the ratio of the electric force to the gravitational force?

Homework Equations



F = Kq1q2/r^2

The Attempt at a Solution



I figured out the 1st part. F = 14 N

but how do i start the 2nd part?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
