In method of determining refractive index of transparent liquid with help of convex lens and plane mirror ,an equi double convex lens of refractive index 1.5 has been taken…. Sir plzzzz tell what is the relation for refractive index of liquid of convex lens and that of combination Can you answer?
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 […]
