The two ends of a long cylinder containing gas are maintained at different temperatures. Which of the following quantities will have the same value throughout the cylinder?

An electric dipole is placed as shown in the figure.

The electric potential (in 10² V) at point P due to the dipole is 

Figure shows a square loop ABCD with edge length a. The resistance of the wire ABC is r and that of ADC is 2r. The value of magnetic field at the centre of the loop assuming uniform wire is :

Addition of trivalent impurity to a pure semiconductor creates many

A satellite of mass M is in a circular orbit of radius R about the centre of the earth. A meteorite of the same mass, falling towards the earth, collides with the satellite completely inelastically. The speeds of the satellite and the meteorite are the same, just before the collision, the subsequent motion of the combined body will be :

A mass of 1 kg is suspended from a spring of force constant 400 N, executing S.H.M. total energy of the body is 2J, then maximum acceleration of the spring will be:

A force F = 20 + 10y acts on a particle in y-direction where F is in newton and y in meter. Work done by this force to move the particle from y = 0 to y = 1 m is :

A bimetallic strip is made of aluminium and steel (α_Al > α_steel). On heating, the strip will

The ratio of total kinetic energy to the rotational kinetic energy of a solid sphere rolling on a horizontal surface is-
