Dr. A! You're a lifesaver! I found you at the perfect time! Thank you so much for these videos.

[@Beza-nn1je]

Wish I found you little bit earlier. 3 days away from my finals and you're helping a lot. Thank you

[@yoprofmatt]

Glad to be helping now. That was definitely the goal of this channel.
Cheers,
Dr. A

Thanks Dr. A! It really helps!

If both Q1 and Q3 were postitive, would it be (Q1+Q3)?

[@hemantdaulta1]

So F23 was -ve because it’s an attractive force acting on 2 due to 3. And Q3 is still negative cause it’s a -ve charge. Thereby resulting in an addition on the magnitude of the resultant force vector.

Correct. Time stamp 4:10
