Coulomb's Law - Square of Charges Example 

Thanks! I was a student once too. I know the pain.

That’s because I am the best! Glad you liked it.

@@danthetutor2624thank you so much for this video.. I have watched more than four different videos on this but still don’t get it.

I have a similar question can I drop it for you sir?

@@udehjosiahsnowwhite7761 I can’t say no to a student. Go ahead.

@@danthetutor2624 thank you so much sir ABCD is a square of 0.04m side. Charges 16 x 10-9, -16 x 10-9 and 32 x 10-9 coulomb are placed at the points A, C and D respectively. Find the electric field strength at point B.

Thanks!
