Answer:
The electric field inside the hollow plastic ball is zero.
Explanation:
According to Gauss's law, the electric field at the closed Gaussian surface
is given by
![$\oint_S {E_n \cdot dA = \dfrac{Q_{enc}}{{\varepsilon _0 }}}$](https://tex.z-dn.net/?f=%24%5Coint_S%20%7BE_n%20%5Ccdot%20dA%20%3D%20%5Cdfrac%7BQ_%7Benc%7D%7D%7B%7B%5Cvarepsilon%20_0%20%7D%7D%7D%24)
Now, to find the electric field inside the hollow plastic ball, we choose a spherical Gaussian surface inside the ball. And since all of the charge lies on the surface of the ball, the Gaussian surface does not enclose any charge; therefore, the Gauss's law gives:
![$ E(4\pi r^2)= \dfrac{Q_{enc}}{{\varepsilon _0 }}}$](https://tex.z-dn.net/?f=%24%20E%284%5Cpi%20r%5E2%29%3D%20%5Cdfrac%7BQ_%7Benc%7D%7D%7B%7B%5Cvarepsilon%20_0%20%7D%7D%7D%24)
![$ E(4\pi r^2)=0$\\\\\boxed{E = 0}](https://tex.z-dn.net/?f=%24%20E%284%5Cpi%20r%5E2%29%3D0%24%5C%5C%5C%5C%5Cboxed%7BE%20%3D%200%7D)
The electric field inside the hollow plastic ball is zero.

Explanation:
my answer basicly sums it up
Both physicians Einstein and Newton explained the gravity.
Einstein described the gravity by suggesting that the space-time around any object is bent, while Newton described gravity by principle of action.,
