Electrons in an oscilloscope are deflected by two mutually perpendicular electric fields in such manner that displacement at any time is given by:
x=X, cos (ot+ )
2.
y=Y, cos ot
i) Use rotating vector technique to sketch the resultant motion produced on
the CRO screen
ii) Use analytical method to determine the equation of the resultant path​
