# AIEEE Physics Solids and Fluids Online Test

A wire elongates by L mm when a load W is hanged from it. If the wire goes over a pulley and two weights W each are hung at the two ends, the elongation of the wire will be (in mm)

A wire fixed at the upper end stretches by length L by applying a force F. The work done in stretching is

A wire suspended vertically from one of its ends is stretched by attaching a weight of 200 N to the lower end. The weight stretches the wire by 1 mm. Then the elastic energy stored in the wire is

If S is stress and Y is Young’s modulus of material of a wire, the energy stored in the wire per unit volume is

Two wires are made of the same material and have the same volume. However wire 1 has cross section area A and wire 2 has cross-section area 3A. If the length of wire 1 increases by dx on applying force F, how much force is needed to stretch wire 2 by the same amount

Spherical balls of radius R are falling in a viscous fluid of viscosity n with a velocity v. The retarding viscous force acting on the spherical ball is

A cylinder of height 20 rn is completely filled with water. The velocity of efflux of water (in m/s) through a small hole on the side wall of the cylinder near its bottom is

If two soap bubbles of different radii are connected by a tube,

A 20 cm long capillary tube is dipped in water. The water rises up to 8 cm. If the entire arrangement is put in a freely falling elevator the length of water column in the capillary tube will be
