As we know that in aeroplane during landing the charged produced in it due to the friction with ground are earthed through its wheels; can this charge be stored with the help of a capacitor and used for useful purpose? Answer: I feel that this is a metter for research. If you feel otherwise and … Continue reading Can the frictional electricity produced during landing of a plane be used for constructive purposes?
HC Verma's Concepts of Physics - Chapter 10 - Question 15 Find the moment of inertia of a uniform square plate of mass m and edge a about one of its diagonals. The question was posted by Ankit Solution: Let the moment of inertia about the axis through the centre of the square plate perpendicular to the plane, assumed to be along … Continue reading Rotational Mechanics – HC Verma’s Concepts of Physics – Solution
