(i) Electric field lines come out of positive charge and go into the negative charge.
(ii) Tangent to the field line at any point gives the direction of the field at that point.
(iii) Field lines never have a collision with one another.
(iv) Field lines are always normal to conducting surface.
(v) Field lines do not be inside a conductor.
(vi) The electric field lines never create closed paths.

What is the shortest possible time in which a bacterium could travel a distance of 8.4 cm across a Petri dish at a constant speed of 3.5 mm/s?
Frequency The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz. V=1/T

Consider a current loop where the circulating current is I. This may be for an example of a coil carrying a current. We will assume that the current loop lies within a single plane
The energy to which the human ears are sensitive is named as sound. In general all parts of waves are produced in an elastic material phase, Irrespective of while these are listen
