Question

A nonuniform electric field is directed along the x-axis at all points in space. This magnitude of

Answer 1

Answer:

E) -0.28 nC

Explanation:

For using Gauss law

we calculate flux through whole cylinder.

• On curved part flux is zero
• On left par flux is =$-\pi *0.1^{2} 2000= -20*\pi$

• On right par flux is =$-\pi *0.1^{2} 1000= 10*\pi$

    Total flux =-10$\pi$

According to Gauss law

net flux along closed surface=  $\int\limits^a_b {E} \, ds=\frac{charge enclosed}{epsilon}$[epsilon =8.85 *$10^{-12}$]

 10$\pi$=$\frac{q enclosed}{epsilon}$

plug in the values

we get charge enclosed = -0.28 nC
