Q1). An isolated system consists of three point charges. Two are negative and one is positive. What can you say about the sign of this system's electrostatic potential energy?
An isolated system consists of three point charges. Two are negative and one is positive. What can you say about the sign of this system's electrostatic potential energy?
you can't tell from the information given
Q2).An electron is first moved perpendicularly away from a large uniformly positively charged plate. Then after removing the electron, the identical movement is repeated with a proton. How do the electric potential differences experienced by each compare?
Q3).A parallel plate capacitor is first connected to a battery for a while and then disconnected from the battery. If a dielectric is then inserted between the plates, what happens to the charge on its plates?
the charge stays the same
I just want the RIGHT answers. Thanks :)
it is positive it is is negative it is zeroyou can't tell from the information given

the electron's is larger the proton's is larger they are the sameQ3).A parallel plate capacitor is first connected to a battery for a while and then disconnected from the battery. If a dielectric is then inserted between the plates, what happens to the charge on its plates?
the charge decreases the charge increasesthe charge stays the same
I just want the RIGHT answers. Thanks :)
Explanation / Answer
1 - you can't tell any from the information.
2- The proton's larger.
3- The charge increase.
