A body having a moment of inertia about its axis of rotation equal to `3 kg-m^2` is rotating with angular velocity of `3 rad s^(-1)`. Kinetic energy of this rotating body is same as that of a body of mass 27 kg moving with a velocity `v`. The value of `v`
A line charge `lambda` per unit length is pasted uniformly onto the rim of a wheel of mass m and radius R. The wheel has light non–conducting spokes and is free to rotate about a vertical axis as shown in figure.A uniform magnetic field B exist as shown in figure. What is the angular velocity of the wheel when the field is suddenly switched off?Consider a conducting circular loop placed in a magnetic field as shown in figure. When magnetic field changes with time, magnetic flux also changes and emf `e=-(dphi)/(dt)` is induced. If resistance of loop is R then
Moment of InertiaA heavy wheel called flywheel is attached to the shaft of steam engine, automobile engine etc., because of its large moment of inertia, the flywheel opposes the sudden increase or decrease of the speed of the vehicle. It allows a gradual change in the speed and prevents jerky motion and hence ensure smooth ride of passengers.A particle of mass `1 kg` is kept at `(1m, 1m, 1m)`. The moment of inertia of this particle about `Z`-axis would
When a ceiling fan is switched OFF, its angular velocity fall to half while it makes 36 rotations. How many more rotations will it make before coming to rest? (Assume uniform angular
AC Generator An AC generator produces electrical energy from mechanical work, just the opposite of what a motor does. In it, a shaft is rotated by some mechanical means, such as an engine or a turbine starts working and an emf is induced in the coil.It is based on the phenomenon of electromagnetic induction which states that whenever magnetic flux linked with a conductor (or coil) changes, an emf is induced in the coil. An AC generator consists of a coil of 1000 turns and cross-sectional area of `100 cm^2`, rotating at an angular speed of 100 rpm in a
