Question
True or false:It is impossible for any onject to have a charge of 7.5e
If one bag contains a charge 8Q and another one contains charge Q, the 8Q bag exerts 8 times as much force on the Q bas as the Q bag exerts on the 8Q bag
Two infinite parallel plastic sheets contain equal negative charge densitties uniformly spread over their surfaces. The electric field is zero everywehre between these sheets, not just midway between them
A dipole is place near to a point charge Q. The net force on this dipole is zer because the dipole is neutral.
A pair of equal but opposite charges is glued to opposite ends of a plastic rod and placed in a uniform electric ffield in such a way that the rod makes a 45 degree angle with the field. The net force and torque on this combination of charges due to the field is zero because the charges balance out.
Explanation / Answer
It is impossible for any onject to have a charge of 7.5e { true] Since charge is quantised.i.e., it is in integral multiples of charge e If one bag contains a charge 8Q and another one contains charge Q, the 8Q bag exerts 8 times as much force on the Q bas as the Q bag exerts on the 8Q bag [ false] Since forces are equal on both charges due to another charge Two infinite parallel plastic sheets contain equal negative charge densitties uniformly spread over their surfaces. The electric field is zero everywehre between these sheets, not just midway between them [ True ] Since electric field due to infinite plastic sheet = s / 2e where s = surface charge density e = permitivity of free space these fields are equal and opposite to each other due to two plastic sheets A dipole is place near to a point charge Q. The net force on this dipole is zer because the dipole is neutral.[ False] A pair of equal but opposite charges is glued to opposite ends of a plastic rod and placed in a uniform electric ffield in such a way that the rod makes a 45 degree angle with the field. The net force and torque on this combination of charges due to the field is zero because the charges balance out. [ False] net force is zero but torque is present
