A meter bridge is set up as shown to determine an unknown resistance X using a standard 10 ohm resistor. The galvanometer shows null point at 52 cm mark. The end corrections are 1 cm and 2 cm respectively for the ends A and B. The determined value of X is
On a hypotenuse of a right angled prism of liquid is placed as shown in the figure. Light is allowed to fall normally on the short face of the prism. In order that the ray of light may be totally reflected, the maximum value of refractive index is
The following figure depicts a circular motion. The radius of the circle, the period of revolution, the initial position and the sense of revolution are indicated in the figure. The simple harmonic motion of the x-projection of the radius vector of the rotating particle P can be shown as
