Question

An AC voltage source of frequency 50 Hz and amplitude v 0 is turned on at time t = 0 . A second voltage source of the same frequency and amplitude is turned on at a later time t = 5 ms. For both sources, the voltage is found to increase immediately after being turned on. The instantaneous voltage of the two sources can be represented respectively by v 1 (t) and v 2 (t), where explain me the method of doing too

Answer 1

An AC voltage source of frequency 50 Hz and amplitude v0 is turned ... same frequency and amplitude are  turned on at a later time t = 5 ms ... A second voltage source of the same frequency and amplitude is turned on at a later time t = 5 ms. For both sources, the voltage is found to increase immediately after ..

Answer 2

Answer:

(a) rα ˃ rd ˃ rp (b) rα= rp˂ rd `` (c) rα= rd ˃ rd (d) rα=

A proton, a deutron and an α- particle having the same kinetic energy are moving in circular trajectories in

a constant magnetic field. If rp, rd and rα denote respectively the radii of the trajectories of these particles,

then

(a) rα ˃ rd ˃ rp (b) rα= rp˂ rd `` (c) rα= rd ˃ rd (d) rα=i

rd = rd
