Q:
      
      
         
            
In spherical polar coordinates (l, q, a), q denotesthe polar angle around z-axis and a denotes the azimuthal angle raised from x-axis . Then the y-component of P is given by
         
       
      
      
      
          
      
      
          Answer & Explanation
         Answer: A) Psinq sina         
         
Explanation: 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
