Q-3: A point charge Q with a velocity v = vox enters a region having a uniform magnetic field B = Bx+Byŷ + B₂2. a) What E field should exist in the region so that the charge proceeds without a change of velocity? (You will find an expression that depends on B and v) b) A circular loop of radius b that carries a direct current "I". Find the magnetic flux density (B) at the center (O) of the circular loop. (Show all symbols you will use on the figure) Q-3 part-b I
