A stone tied to a string of length l is whirled around a vertical circle with the other end of the string at the centre. At a certain instant of time the stone is at the lowest position and has a speed u. What is the magnitude of change in its velocity as it reaches…… Continue reading Motion in a vertical circle and conservation of energy
Centroid is the geometric centre of a plane figure or object Centroid divides the shape into regions of equal moments. Centre of mass is the mean location of all masses in a system Centre of gravity is the point through which the w…
Rajkumar asks: “accelaration due to gravity decrease on depth of earth with the relation of g’=g(1-2h/R). but with relation of g=GM/(R*R) g increase.
When the object is on the surface or above it, the entire mass of the earth attracts it. But when it is inside, the net attraction towards CENTRE is provided only by the mass of […]

Time: 45 min Max. Marks: 25 How does the force between two point charges change, if the dielectric constant of the medium in which they are kept, increases?  Name the experiment which established the quantum nature of electric charge.  Ordinary rubber is an insulator, but the special tyres of aircrafts are made slightly conducting. Why…… Continue reading Electrostatics : A Practice Test Paper – 1
An infinite no. of charges each equal to 4 micro coulomb are place along the x-axis at x=1m,2m,4m and so on.find the electric field at the origin due to given sets of charges. What is meant by a cavity and what is the electric field on the circumference of a cavity whose centre is at…… Continue reading Some Questions from Electrostatics posted by visitors
