The capacity of a parallel plate condenser is `50pF`. A magnetic field of `4xx10^(-7)T` is produced at a distance of `10cm` from the axis of the gap. The charging current is

What is the current in a straight wire, if a magnetic field of 10^(-6)W//m^(2) is produced at a distance of 2 cm from it ?

The capacity of a parallel plate condenser consisting of two plates each 10cm square and are separated by a distance of 2mm is

The capacity of a parallel plate condenser is 10 muF without dielectric. Dielectric of constant 2 is used to fill half the distance between the plates, the new capacitance in muF is

The bar magnet produces magnetic induction of 4xx10^(-5)T at a point 10 cm from centre on the axis of magnet.The magnetic moment is

The capacity of a parallel plate condenser with dielectric constant 10 is 16xx10^(-6)F . If the dielectric is removed, then the new capacity will be

The capacity of a parallel plate condenser consisting of two plates each 10 cm square and are seperated by a distance of 2 mm is (Take air as the medium between the plates).

The capacity of a parallel plate condenser is 15 mu F when the distance between its plates is 6 cm. if the distance between the plates is reduced to 2 cm, then the capacity of this prarallel condenser will be

The capcity of a parallel plate condenser is 10 muF , when the distance between its plates is 8 cm . If the distance between the plates is reduced to 4 cm , then the capacity of this parallel plate condenser will be
