Q. The electric field due to a uniformly charged spherical shell outside the shell is as if

कोश के बाहर एकसमान रूप से आवेशित गोलाकार कोश के कारण विद्युत क्षेत्र इस प्रकार होता है

Charge is spread on the surface
आवेश सतह पर फैला हुआ है

Charge is concentrated at center
आवेश केन्द्र पर केन्द्रित होता है

Zero
शून्य

Inversely proportional to r²
r² के व्युत्क्रमानुपाती

Outside a spherical shell, the electric field behaves exactly like the field due to a point charge placed at the center of the shell:

E = \frac{1}{4 π ε_{0}} \cdot \frac{q}{r^{2}}

So, for external points, the shell behaves as if entire charge is concentrated at the center.
