55. In spherical polar coordinates (l, q, a), q denotes the polar angle around z-axis and a denotes the azimuthal angle raised from x-axis . Then the y-component of P is given by A.Psinq sina B.Psinq cosa C.Pcosq sina D.Pcosq cosa
Option A Solution: The Cartesian Coordinates can be retrieved from spherical coordinates (l,q,a) by: X = r.sinq.cosa Y = r.sinq.sina Z = r.sinq Using the same we get for P, Y = P.sinq.sina
