In designing a velocity selector that uses uniform perpendicular electric and magnetic fields, you want to select positive ions
of charge that are traveling perpendicular to the fields at 8.75 km s. The magnetic field available to you has a magnitude of 0.550 T. (a) What magnitude of electric field do you need? (b) Show how the two fields should be oriented relative to each other and to the velocity of the ions.
Since the car is at rest, the force experienced by car will be normal face(exerted by surface to which car is in contact) and weight of the car. As the car is at rest, net force on the car should be zero.
In a full wave rectifier, the fundamental frequency of the ripple is twice that of input frequency. Given the input frequency of 50 Hz, the fundamental frequency will be 2 × 50 = 100Hz
