A sphere with charge Q was placed in, but not touching a larger hollow sphere. If there is any charge initially on the outer sphere; to remove it the outer sphere was earthed momentarily, and then the

Consider an arbitrary distribution of conducting bodies in a charge free space according to the uniqueness theorem, which of following are required to be specified in order that the field is uniquely

A plane mirror is placed along the y-axis as such x-axis is normal to the plane of the mirror. The reflecting surface of the mirror is towards negative x-axis. The reflecting surface of the mirror is

In presence of a charged body, an insulated conductor develops positive charge at one end and negative charge at another end. This process is called

A charge distribution has the charge density given by ρ = Q{δ(x - x0) - δ(x + x0)}. For this charge distribution the electric field at (2x0, 0,0)

A point charge of 6 μC is located at the origin, uniform line charge density of 180 nC/m of 8 m length lies along the x axis and a uniform sheet of charge equal to 25 nC/m2 of area p x 42 lies in the

In an experiment, positive and negative values are equally likely to occur. The probability of obtaining at most one negative value in five trials is

If the product of 6 integers is negative, at most how many of the integers can be negative

Negative divided by Negative

The input to negative clamper has a peak value of Vp. Then in the output the positive and negative peaks are nearly
