An infinite line of charge with linear density A, = 6.6 uC/m is positioned along the axis of a thick insulating shell of inner radius a = 2.4 cm and outer radius b = 4.7 cm. The insulating shell is ..XO uniformly charged with a volume density of p = -744 uC/m]. X70 1) What is A2, the linear charge density of the insulating shell? UC/m Submit 2) What is Ex(P), the value of the x-component of the electric field at point P, located a distance 7.2 cm along the y-axis from the line of charge? N/C Submit 3) What is E,(P), the value of the y-component of the electric field at point P, located a distance 7.2 cm along the y-axis from the line of charge? N/C Submit 4) What is Ex(R), the value of the x-component of the electric field at point R, located a distance 1.2 cm along a line that makes an angle of 30 with the x-axis? N/C Submit 5) What is Ey(R), the value of the y-component of the electric field at point R, located a distance 1.2 cm along a line that makes an angle of 30 with the x-axis? N/C Submit 6) For how many values of r: (2.4 cm < r < 4.7 cm) is the magnitude of the electric field equal to O? Onone one more than one Submit 7) If we were to double A, (2, = 13.2 uC/m), how would E, the magnitude of the electric field at point P, change? OE would double OE would increase by more than a factor of two OE increases by less than a factor of two OE decreases by less than a factor of two OE decreases by more than a factor of two Submit 8) In order to produce an electric field of zero at some point r > 4.7 cm, how would , have to change? Change its sign and increase its magnitude Change its sign and decrease its magnitude Keep its sign the same and increase its magnitude Keep its sign the same and decrease its magnitude Submit
