What is the minimum distance that a man has to run to reach point B from point A in the circular field with its center at O and radius 500 yards, ? => 50 yards or 2000 y..

Magnetic Field due to a Current Carrying Circular Loop - The demonstration given below explains the nature of magnetic field due to a current carrying circular loop. Procedure Observation Take a long wire and bend it to form a circle Concentric circles are fo..

During motion in a straight line, the point object occupies a definite position on the path at each instant. Therefore, to describe the motion, one should specify the length of the path covered by the point object and the instant of time. The length of path covered by the object..

Toroid is a hollow circular ring (like a medu vadai) on which a large number of turns of a wire are wound. The above figure represents a toroid wound with a wire carrying a current I. Consider path 1, by symmetry , if there is any field at all in this region, it will be tangent ..

Rules for Determining the Direction of Magnetic Field - The direction of magnetic field around a current carrying conductor can be determined by using one of the laws given here. Rule Pictorial Representation Right Hand Thumb Rule Imagine that you are holding the conductor in yo..

Potential due to a Point Charge - Consider two points 'a' and 'b' in an electrostatic field of a single isolated point charge +..

Consider a hollow conducting sphere of radius R with its centre at O. let s be its surface density. The field at any point P, outside or inside depends upon the distance from the centre of the spherical shell. Let the distance between the centre ..

. It is seen that the frequency, which makes a given distance correspond to the skip distance, is the MUF for that pair of points. At the skip distance, only the normal or lower ray can reach the destination, whereas at greater distances, ..

Suppose a bus starting from a terminus A travels 15000 m to reach terminus B. Then the distance covered by the bus is 15000 m. Now if the bus returns to the terminus A, then what is the distance covered by the bus during the return trip? The di..

Points A (2, 0), B(3, - 2), C(2, - 4) and D(0, - 4) are dilated to A′, B′, C′, and D′ under O(0, 0) as the center and scale factors 2.5, 2, 1.5 and 1.5 respectively. Which of the following figures represents A′B&pr..
