A simple problem

Place an opaque "blob" of charge on a transparent, hemispherical nonconducting shell, as shown.

. Find z component of field due to it, at centre O.

Do check out www.webofstories.com, listening to those great men (and women, of course) is a humbling experience.

@Kishore S Shenoy (vector = scalar ?) Yeah, you are right. The result is trivial, but has applications. For example, if we want to calculate field due to a hemispherical shell of charge at the centre, without messy integration. Karthik Venkata · 5 months, 2 weeks ago

@Karthik Venkata Yeah, I know. That's the beauty of nature's dimensional analogy! Kishore S Shenoy · 5 months, 2 weeks ago

Is it \(\vec{E} = \dfrac{\sigma A}{4\pi\epsilon_0 r^2}\hat{e_z}\)? Kishore S Shenoy · 5 months, 2 weeks ago
