Why dielectric constant effect electrostatic force, what is its significance?

a square with sides 10cm has three charges on it edges, two are+5mC and one is -3mC. draw a well labelled diagram to illustrate the question and compute the total field at the vacant edge due to the other charges

A charge _q is distributed uniformly over a sphere with a positive charge q at its centre.Also the same situation for an ellipsoid ..with respect to the origin of the coordinate system find the correct statement

(a)dipole moment is zero for both cases (b)dipole moment non zero for 1st case but zero in next case (c)dipole moment zero for 1st case but non zero in next case (d ) non zero both cases

If a virtual image is formed along the principal axis 10 cm from a concave mirror with focal length 15 cm what is the object distance from the mirror

The orbital speed of electron orbiting around the nucleus in a circular orbit of radius 50Pm is 2.2x 106 m/s, the magnetic dipole moment of an electron is

An alpha particle, of charge +3.2 × 10−19 C and velocity of magnitude 500 m/s, travels horizontally into a region of space in which there is an upward-directed uniform electric field of magnitude 20 N/C and a uniform magnetic field. The magnetic field makes an angle of 40° with the particle’s velocity vector, and is such that it causes the alpha particle to pass through the region of space undeflected.

Beginning with an explanation of what happens to the alpha particle in the presence of the electric field, explain clearly how the presence of the magnetic field causes the alpha particle to pass through undeflected.

Determine the magnitude of the magnetic field that is required to cause the alpha particle To pass through undeflected

Is there other ways to see the magnetic field lines around the bar magnet ?

A plane e.m. wave is travelling in an lossless dielectric medium having μ = 2, ε = 3

and has peak value electric field intensity of 6 V/m . The velocity of wave is
