Question

0/10 pts Suppos¢ the electric potential due to Coordinate% as certain charge distribution can be written in Cartesian what is the rragnitude of the electric field at the point (1,1,1)? Your answre?should not include units. And write your answer in two decimal places Question 2 0 10 pts A thin rod extends along the z-axis from z “-d to z-d . The rod carries a positive charge Q uniformly distributed along its length 2d with charge density ?-563 C/m-what is the change in electrostatic potential energy if electrons move from z-3d toz-4d?Take elementary charge 1.6x101 C and take Coulomb's constant 9x10 Nm2C2). Write your answer in multiples of 10-10 Nm Your result must contain 2 figures after the decimal point Question 3 0 10 pts Consider a metallic spherical shell of radius 21.66 mm and charge 8.17 uC, as shown in Figure. Find the electric potential inside the shell(Take Coulomb's constant 9x10 Nm2c2) Write your answer in multiples of 10 Nm/C. And write your answer in two decimal places

Explanation / Answer

3)

r = radius of the spherical shell = 21.66 mm = 0.02166 m

Q = charge = 8.17 x 10-6 C

electric potential inside the shell is given as

V = k Q/r

V = (9 x 109) (8.17 x 10-6 )/(0.02166 )

V = 3.4 x 106 Volts
