Physics | Electrostatics | Calculating the charge on a sphere

[@sowhoisgeh5631]

Intelligent man, thank you for making me understand this chapter. Writing Physics next week Friday, incredibly helpful.

[@milo_drogba]

I'm writing Physics tmrw, your doing a great job thank you sir🙏

[@MlungisiNkosi]

Most welcome

is in grade 12 in 2021 but still watching this even at varsity . Thanks sir

[@MlungisiNkosi]

Wow that’s great to hear that

[@happytagged7724]

🙌the cookie is definitely crumbling sir😂❤ thnk u

[@MlungisiNkosi]

I'm glad 😂

[@ThabisoMkhize-ye3vf]

Sir if i may ask we only use signs in when calculating charges and not when calculating the net electrostatic force

[@LusihleMbovu]

Yes in net electrostatic force we only care about direction but on charges it signs

[@ThandazileGumede-x3u]

Thank you sir i really understand you made it so understandable 🥰

[@Shaili_soodyall]

Sir, would we not say -1,27 x 10^-6 = 150Qr - (-450Qr) ?

[@sivunyasulu4874]

This was very helpful. Thank-you😇

[@MlungisiNkosi]

You're welcome

[@ian_sambo04]

Good day sir. I have a question.
When you say -450Qr and 150QR would it be marked correct even if we don't include the unit of N?

[@MlungisiNkosi]

Please include SI units

[@reabetswemawela5508]

So sir if they don't tell us the charge of a sphere should we just assume it's positive , because for R they didn't tell us the charge and you said it's positive

[@MlungisiNkosi]

Well, they will tell you if it’s positive or negative.

writing a 150 mark test tomz thanks sir

[@MlungisiNkosi]

All of God's best Andile... I know you'll do well.

[@danxgaming8709]

Sir can I say that the final answer is 4.23nC

[@MlungisiNkosi]

Yep

[@boitumelomotlohi2495]

Thank you sir
