Which is the magnitude of an electric field intensity that will balance?
What is the magnitude of electric field intensity that balances the weight of an electron.It is given that e=1. 6×10−19C and me=9.
What are the magnitude and direction of the electric field that will balance the weight of an electron and proton?
What are the magnitude and direction of the electric field that will balance the weight of the following? For an electron/proton we use the equation qE=mg. Therefore the answer for magnitude would just to multiply the mass of an electron/proton by 9.8.
Can two electric lines of force intersect?
Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible.
What is the magnitude of the electric field strength E such that an electron placed in the field would experience an electric force equal to its weight?
The magnitude of electric field intensity E such that an electron placed in it would experience an electrical force equal to its weight is given by ….. therefore electric field intensity E is given by mg/e. option (b) is correct choice.
What electric field strength is needed to support an electron against gravity What should be the direction of the electric field?
An electron is suspended in space just close to the ground and it has a charge of 1.60 times 10 to the minus 19 coulombs— negative because it’s an electron— and the electrostatic force upwards is equal to the force of gravity downwards and because the electrostatic force is upwards, this means the electric field …
What is the magnitude of a point charge which produces an electric field of 2?
2×10−12 coulomb.
What is the magnitude of the electric force on the point charge?
The electrostatic force exerted by a point charge on a test charge at a distance r depends on the charge of both charges, as well as the distance between the two. The electric field E is defined to be E=Fq E = F q , where F is the Coulomb or electrostatic force exerted on a small positive test charge q.
What is the charge of point charge?
A point charge is an electric charge. When the linear sizes of charged bodies are much smaller than the distance between them, their sizes may be ignored and the charged bodies are called point charges.
What is point charge in simple words?
an electric charge considered to exist at a single point, and thus having neither area nor volume.
How much work is doing in moving a charge of 2c from a point of 118 V to a point of 128v?
Answer. The correct answer is (A) 20 J.
How much energy is given to each?
Ans: The energy given to each coulomb of charge is equal to the amount of work which is done in moving it. Now we know that Potential difference =Work done / Charge ∴ Work done = Potential difference × charge Where, Charge = 1 C and Potential difference = 6 V ∴ Work done = 6×1 = 6 Joule.
How much energy is given to each col?
The energy given to each coulomb of charge is equal to the amount of work required to move it.
How much energy does a 12v power supply transfer?
Answer. So 12 J energy is transferred by a 12 V power supply to each coulomb of charge which it move around a circuit .
