 Orbital Velocity of Satellite

Satellites are natural or artificial bodied describing orbit around a planet under its gravitational attraction. Moon is a natural satellite while INSAT – 1B is an artificial satellite of earth. Condition for establishment of artificial satellite is that the center of orbit of satellite must coincide with center or earth or satellite must move around Read more about Orbital Velocity of Satellite[…] Equation of Line passing through Two given Points

From the figure, and . Since is collinear with , for some scalar λ, we have . or . or … (i) Therefore, the equation of a straight line passing through and is . We have and . Substituting these values in (i), we get . Equating the coefficients of , and , we get Read more about Equation of Line passing through Two given Points[…] Vignan’s Scholastic Aptitude Test (VSAT) 2020 Notification Released

The physical quantities may be broadly classified into the vectors and the scalars. The quantities with magnitude and direction both are known as vector quantities, it means a vector is a physical quantity that has both magnitude and direction. If two non-zero vectors are represented by the two sides of a triangle taken in same Read more about Triangle Law of Vector Addition of Two Vectors[…] Vectors – Equation of Straight Line

Equation of Straight Line passing through a given Point and Parallel to a given Vector Vector Form: Line passing through point and parallel to vector . Let A be the given point and let AP be the given line through A. Let  be any vector parallel to the given line. Position vector of point A Read more about Vectors – Equation of Straight Line[…] Cylindrical Capacitor

Cylindrical Capacitor A cylindrical capacitor consists of two coaxial cylinders of radii a and b, say b > a. The outer one is earthed. The cylinders are long enough so that we can neglect fringing of electric fields at the ends. The electric field at a point between the cylinders will be radial, and its Read more about Cylindrical Capacitor[…] Homogeneous Differential Equation

Homogeneous Differential Equation A differential equation is said to be a homogeneous differential equation in x, y if both f (x, y), g (x, y) are homogeneous function of same degree in x and y. To find the solution of the Homogeneous Differential Equation put y = v x, then . Substituting these values in Read more about Homogeneous Differential Equation[…] Sathyabama University All India Engineering Entrance Exam (SAEEE) 2020 Notifications Released
