4.A charge distribution in free space hasp, = 2rnC/m for 0 Srs 10mand zero otherwise. Determine E at r= 2m andr 12m. 5.Ring placed along y2 + z? = 4, x = 0 carries a uniform charge of 5 µC/m. (1) Find D at P(3,0, 0). (2) If two identical point charges Q are placed at(0,-3,0)and (0,3,0) in ad- dition to the ring,find the value of Q such that D =0 at P. 4.A charge distribution in free space hasp, = 2rnC/m for 0 Srs 10mand zero otherwise.
