When a body A of mass m is resting on a body B of mass M then two conditions are possible: 1) A force F is applied to the upper body, and then following four situations are possible: (a) The body A will move on body B with acceleration (F/m): . (b) The body B Read more about Motion of two bodies one resting on the other[…]
Foot of perpendicular from a point on the given Line: Here, the equation of line AB is . Let L be the foot of the perpendicular from P (α, β, γ) on the line . Let the coordinates of L be (x₁ + aλ, y₁ + bλ, z₁ + cλ). Then the direction ratios of Read more about Perpendicular Distance of a Point from a Line – Cartesian form[…]

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[…]
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 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[…]
