Intensity of Gravitational Field The intensity of the gravitational field of a body at a point in the field is defined as the force experienced by a body of unit mass placed at that point provided the presence of unit mass does not disturb the original gravitational field. It is always directed towards the centre Read more about Intensity of Gravitational Field[…]

Multinomial Theorem Consider the equation x₁ + x₂ + … + xᵣ = n, where aᵢ ≤ xᵢ ≤ bᵢ; xᵢ ϵ 1; I = 1, 2, …, r. In order to find the number of solutions of the given equation satisfying the given condition. We observe that the number of solutions is the same Read more about Multinomial Theorem[…]
Horizontal Range of the Escaping Liquid Water stands at a depth H in a tank whose sides are vertical. A hole is made in one of the walls at a depth h below the water surface. Let container remains at rest. When the liquid remains emerges out of the hole, it goes along a parabolic Read more about Horizontal Range of the Escaping Liquid[…]
Force of Reaction due to Ejection of Liquid A cylindrical vessel has an opening of cross-sectional area “a” near the bottom. A disc is held against the opening to prevent liquid of density ρ from coming out. If the height of the liquid above opening is h. Let us analyse the force on the disc Read more about Force of Reaction due to Ejection of Liquid[…]

Vector form of Newton’s Law of Gravitation Newton’s Law of Gravitation states that everybody in this universe attracts every other body with a force which is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them. Consider two points mass bodies A and B of Read more about Vector form of Newton’s Law of Gravitation[…]
Combination – Properties of ⁿCr Each of the different groups of selections, which can be made by taking some or all of a number of given things or objects at a time is called a combination. In combination, order of appearance of things is not taken into account Example: Three groups can be made with Read more about Combination – Properties of ⁿCr[…]
