Figures \((a) \)and \((b)\) show the field lines of a positive and negative point charge respectively.

Does the kinetic energy of a small negative charge increase or decrease in going from \(B\)  to \(A\) ?

Four charges are arranged at the corners of a square \(\mathit{ABCD}\)  of side d. as shown in the figure. Find the work required to put together this arrangement.
A compound microscope consists of an objective of focal length 1.0 cm and an eyepiece of focal length 5.0 cm separated by 12.2 cm. Calculate the angular magnification in this case.
Four charges are arranged at the corners of a square  \(\mathit{ABCD}\)  of side\( d\). as shown in the figure.  \(A\)  charge  \(q_0\)  is brought to the centre  \(E\)  of the square, the four charges being held fixed at its corners. How much extra work is needed to do this?

Vehicles carrying inflammable materials usually have metallic ropes touching the ground during motion. Why?
The magnifying power of a converging lens used as a simple microscope is \( \left(1+\frac{D}{f}\right)\). A compound microscope is a combination of two such converging lenses. Why don't we have magnifying power \( \left(1+\frac{D}{{f}_{o}}\right)\) \( \left(1+\frac{D}{{f}_{e}}\right)\)? In other words, why can the objective not be treated as a simple microscope but the eyepiece can?
A bird perches on a bare high power line and nothing happens to the bird. A man standing on the ground touches the same line and gets a fatal shock. Why?
A slab of material of dielectric constant  \(K\)  has the same area as the plates of a parallel-plate capacitor but has a thickness  \(\left(\frac 3 4\right)d\) , where  \(d\)  is the separation of the plates. How is the capacitance changed when the slab is inserted between the plates?
A simple microscope has a magnifying power of 3.0 when the image is formed at the near point (25 cm) of a normal eye. What is its focal length and what will be its magnifying power if the image is formed at infinity?

A network of four \(10\;\mathit{\mu F}\) capacitors is connected to a \(500\;V\) supply, as shown in figure. Determine the equivalent capacitance of the network.
