In a parallel plate capacitor set up, plate area of capacitor is 2 m² and the plates are separated by 1m. If the space between the plates are filled with a dielectric material of thickness 0.5 m and area 2 m² (See fig) the capacitance of the set-up will be ______ ε₀. (Dielectric constant of the material = 3.2) (Round off to the Nearest Integer)

 

A positive charge is moved from low potential point A to a high potential point B. Then the electric potential energy

Two waves of wavelength 50 cm and 51 cm produced 12 beats per second. The velocity of sound is

A parallel plate capacitor is charged and then charging battery is disconnected. If the plates are now pulled apart with insulated handles

Energy stored in circuit 1 is E. If capacitors in circuit 1 and circuit 2 are connected in parallel as shown, the energy stored becomes $\frac{xE}{6}$ , find x.

Potential due to electric dipole on axial position at distance r from dipole is proportional to (assume r >> length of dipole)
