Question

One main scale division otf a Vernier calliper is equal to 1 mm and the number of divisions on the Vernier scale is 10. When both the jaws touch each other, the Vernier scale shifts to the left of zero of the main scale in such a way that 4™ Vernier division coincides with a division of the main scale. If this Vernier calliper measures the length of a wire to be 1 cm, the actual length of the wire is :

A solid sphere A of radius R and mass M is attached at a point to a smaller solid sphere B of radius r < R and mass m < M. Assume that the line joining their centres lies along the horizontal. The moment of inertia of the system calculated about a vertical axis passing through the centre of A is I, and that calculated about a vertical axis passing through the centre of B is I. The difference [,— 1; is : i, . CRE:

Consider a spring mass simple harmonic oscillator in one dimension. The mass of the particle is m kg and the spring constant is k Nm™. At a given instant, the extension of the spring is x meter and the speed of the particle is v ms™. On the x-v plane, if the graph of v as a function of x is a circle, then the correct option is : Mm k=1 2 k=m m
