How can you prove the converse of the above theorem. " If a line in the plane of a circle is perpendicular to the radius at its endpoint on the circle, then the line is tangent of the circle ".
The tangent at any point of a circle is perpendicular to the radius through the point of contact.
Can we draw two tangents perpendicular to each other on a circle ?
The radius of gyration of a uniform disc about a line perpendicular to the disc equals to its radius. Find the distance of the line from the centre.
Find the radius of gyration of a circular ring of radius r about a line perpendicular to the plane of the ring and passing through one of this particles.
Choose the correct answer and give justification for each. (i) The angle between a tangent to a circle and the radius at the point of contact is
Tangent to a curve intercepts the y-axis at a point P A line perpendicular to this tangent through P passes through another point (1,0). The differential equation of the curve is
Find the radius of gyration of a disc of mass M and radius R rotating about an axis passing through the center of mass and perpendicular to the plane of the disc.
In the adjoining figure, point P is the centre of the circle and line AB is the tangent to the circle at T . The radius of the circle is 6 cm . Find PB if angleTPB=60^(@)
