What is the deviation produced by a thin lens of a ray passing through the optical centre?

Why is it easier to rotate a disc than a ring of the same mass and size, about an axis passing through their centres?

Find the moment of inertia of a thin circular ring about an axis passing through the centre and perpendicular to the plane of the ring

Name the factors on which the deviation produced in the path of a ray oflight by a prism depends.

Prove that the perpendicular at the point of contact to the tangent to a circle passes through the centre.

What is the magntiude of transverse acceleration produced in the motion of the electric charge, when it passes through the electric field?

Prism A prism is a portion of transparent refracting medium bounded by two plane surfaces inclined to each other at a certain angle, and the angle between the refracting faces is called angle of the prism denoted by A. The deviation produced by the prism is maximum for violet (delta_v) and minimum for red (delta_r) colour. The deviations suffered by a ray in passing through a small angled prism is

Find the equation of a circle with centre (2,2) and passes through the point (4,5).

Find the differntial equation of all circles which pass through the origin and whose centres lie on x-axis.
