List of top Physics Questions on Electric Field asked in NEET (UG)

એક પોઇન્ટ ચાર્જ \( Q \) એક સોલિડ આઇસોલેટેડ વાહક ગોળામાં કેવિટીની અંદર મૂકેલો છે. બિંદુ A, B અને C ને ધ્યાનમાં લો. સાચો વિકલ્પ છે:

An electron (mass \(9 \times 10^{-31}\) kg and charge \(1.6 \times 10^{-19}\) C) moving with speed \(c/100\) (\(c\) = speed of light) is injected into a magnetic field of magnitude \(9 \times 10^{-4}\) T perpendicular to its direction of motion. We wish to apply a uniform electric field \( \vec{E} \) together with the magnetic field so that the electron does not deflect from its path. (speed of light \(c = 3 \times 10^8\) m/s):

The dimensions [MLT^-2A^-2] belong to the:

A copper wire of length 10 m and radius \((\frac{10^{-2}} { √π})\) has electrical resistance of 10 Ω. The current density in the wire for an electric field strength of \((\frac{V}{m})\) is:

Two point charges -q and +q are placed at a distance of L, as shown in the figure.

The magnitude of electric field intensity at a distance R (R>>L) varies as:

A dipole is placed in an electric field as shown. In which direction will it move

An electron falls from rest through a vertical distance h in a uniform and vertically upward directed electric field E. The direction of electric field is now reversed, keeping its magnitude the same. A proton is allowed to fall from rest in it through the same vertical distance h. The time of fall of the electron, in comparison to the time of fall of the proton is

A toy car with charge q moves on a frictionless horizontal plane surface under the influence of a uniform electric field \(\overrightarrow{E}\) . Due to the force q\(\overrightarrow{E}\), its velocity increases from 0 to 6 m/s in one second duration. At that instant the direction of the field is reversed. The car continues to move for two more seconds under the influence of this field. The average velocity and the average speed of the toy car between 0 to 3 seconds are respectively

A conducting sphere of radius R is given a onducting charge Q. The electric potential and the electric field at the centre of the sphere respectively are:

A, B and C are three points in a uniform electric field. The electric potential is

When a proton is released from rest in a room, it starts with an initial acceleration $a_0$ towards west. When it is projected towards north with a speed $v_0$ it moves with an initial acceleration 3$a_0$ toward west. The electric and magnetic fields in the room
