Rolling of a Body on an Inclined Plane A rigid body of radius of gyration (k) and radius (R) rolls down a plane inclined at an angle (θ) with the horizontal. When a body is placed on an inclined plane, it tries to slip down and hence a static friction (f) acts upwards. This friction Read more about Rolling of a Body on an Inclined Plane[…]

Permutations and Combinations – Division of Objects into Groups Division of items into groups of unequal size: Number of ways in which (m + n)! distinct items can be divided into two unequal groups containing m and n items is (m + n)! / (m!. n!). The number of ways in which (m + n Read more about Permutations and Combinations – Division of Objects into Groups[…]
Moment of Inertia of a Triangular Lamina about its Base Inertia is a property of a body to resist the change in linear state of motion. It is measured by the mass of the body. The moment of inertia (I) of a body is a measure of its ability to resist change in its rotational Read more about Moment of Inertia of a Triangular Lamina about its Base[…]

Coulomb’s Law in Vector Form Charles Coulomb’s measured the magnitude of electric forces between charged objects using the torsion balance. From Coulomb’s experiments, we can generalize the properties of the electric force. Let, and be two like charges placed at points and, respectively, in vacuum. is the position vector of point, and is the position Read more about Coulomb’s Law in Vector Form[…]
Factorial of a Non – Negative Integer If n is a non-negative integer then factorial n is denoted by n! (or) n defined as follows (i) 0! = 1 (ii) If n > 0 then n! = n (n – 1)! The number of permutations of n dissimilar things taken all at a time is Read more about Factorial of a Non – Negative Integer[…]
Mean and Median Mean: The sum of all the observation is divided by the number of observations is called mean and it is denoted by x̅. (i) Mean of ungrouped (or) individual data. If x₁, x₂, …, xn are n observations, then mean x̅ (ii) Mean of grouped (or) continuous data. Whose corresponding frequencies are Read more about Mean and Median[…]
