Forty-one forks are so arranged that each produces 5 beat/s when sounded with its near fork. If the frequency of last fork is double the frequency of first fork, then the frequecies of Forty-one forks are so arranged that each produces 5 beat/s when sounded with its near fork. If the frequency of last fork [...]

A graph of the x-component of the electric field as a function of x in a region of space is shown in figure. The y−andz−compo≠nts of the electric field are zero in this region. If the electric potential is 10 V at the origin, then the potential at x = 2.0 m is A solid [...]
