The field between the plates is 2 × 10 4 V/m. If the space between the plates is filled with a material of relative dielectric constant of 10.0, then the value of the field in the dielectric will be In a hundred-turn coil, if the flux through each turn is (t 3 - 2t) mWb, the magnitude of the induced emf in the coil at a time of 4s is: The fastest ADC among the following is
