AI Thread Summary
To determine how many electrons must be transferred from a negatively charged plate (-3.0 µC) to a positively charged rod (+2.0 µC) so that both objects have the same charge, the final charge on each object must be equal. The solution involves calculating the total charge and then dividing by the elementary charge of an electron (approximately 1.6 x 10^-19 C). The teacher's final answer of 1.6 x 10^13 electrons indicates that this is the number of electrons needed for charge equalization. The discussion emphasizes collaboration in solving the problem rather than providing direct answers. Understanding the charge transfer process is crucial for solving similar physics problems.

Homework Statement



Hi everyone, would you kindly help me with our homework..Although our teacher was able to give the final answer but he couldn't find a solution that will result to the answer.tsk tsk tsk. Here is the problem.


A Plate carries a charge of -3.0 uC, while a rod carries a charge of +2.0 uC. How many electrons must be transferred from the plate to the rod, so that both object have the same charge?

The final answer given by the teacher is:

1.6 x 10 exp 13 electrons

Would you kindly give me the solution on how the book came up with this answer? Many thanks..cheers!

Welcome to PhysicsForums!

We don't do your homework for you here, but we'll work with you. First off, when they're touched together, what happens? What is the final charge on each object? How many electrons is this?
 
electrons are transferred to the other material.. Final charge for plate = 4.8 x10 exp-25
for rod is -3.2 x 10exp-25...Im not sure if this is correct...would you kindly check.tnx
 
up for now

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}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
