electrostatic field lines cannot be discontinuous why?
An electron falls through a distance of 1.5 cm in a uniform electric field of magnitude 2.0 × 104 N C–1 in the direction of the field . Then the direction of the field is reversed keeping its magnitude unchanged and a proton falls through the same distance . compute the time of fall in each case.
project to study various factors on which the internal resistance emf of a cell depends
state Gauss' law in electrostatics.
What is the angle between the directions of electric field at any 1) axial point 2) equatorial point due to an electric dipole ?
State and prove Gauss Theorem.
what are the physical significance of electric field??
Explain the formulae E = Sigma / Epsilon not.
E is the electric field vector.
Epsilon not is the specific inductive capacity or relative permittivity of vaccum.
Sigma = ? (doubt)
the sum of two point charges is 7uC. they repel each other with a force of 1N when kept 30cm apart in free space. calculate the value of each charge.
If E=6i+3j+4k, calculate the electric flux through a surface of area 20 units in the YZ plane.
what is the source charge and test charge
HOW TO DO THIS QUESTION?
The electric field components due to a charge inside the cube of side 0.1 m are as shown:
