MCQ

A far sighted man who has lost his spectacles, reads a book by looking through a small hole ($3-4 \,mm$) in a sheet of paper. The reason will be

A
Because the hole produces an image of the letters at a longer distance
B
Because in doing so, the focal length of the eye lens is effectively increased
✓
Because in doing so, the focal length of the eye lens is effectively decreased
D
None of these

✓

Answer

Correct option: C.

Because in doing so, the focal length of the eye lens is effectively decreased

c
(c) Man is suffering from hypermetropia. The hole works like a convex lens.

The blocks are in equilibrium. The friction force acting on $10 kg$ block is :

A stick of length $L$ and mass $M$ lies on a frictionless horizontal surface on which it is free to move in any ways. A ball of mass $m$ moving with speed $v$ collides elastically with the stick as shown in the figure. If after the collision the ball comes to rest, then what should be the mass of the ball ?

A smooth sphere $A$ is moving on a frictionless horizontal plane with angular speed $\omega $ and center of mass with velocity $v$. It collides elastically and head-on with an identical sphere $B$ at rest. Neglect friction everywhere. After the collision, their angular speeds are ${\omega _A}$ and ${\omega _B}$ respectively. Then

A thin $1 \,m$ long rod has a radius of $5\, mm$. A force of $50\,\pi kN$ is applied at one end to determine its Young's modulus. Assume that the force is exactly known. If the least count in the measurement of all lengths is $0.01\, mm$, which of the following statements is false ?

A wire of mass $m$ and length $l$ can slide freely on a pair of smooth, vertical rails (figure). A magnetic field $B$ exists in the region in the direction perpendicular to the plane of the rails. The rails are connected at the top end by a capacitor of capacitance $C$ . The acceleration of the wire neglecting any electric resistance is
