You're totally right Oniza! 0.01m^2 is in the denominator, and the student performing the calculation squared the 0.01 instead of realizing that it was simply the unit that was squared. And I didn't catch it. I'll be refilming these this next school year and won't repeat this error. Thanks for the heads up!
@@ChadsPrep Hi! I was working through the problem but I think that 89.9N as the force is correct. You need to square the radius in the denominator, and although you wrote the units as 0.01m^2, wouldn't the correct layout be (0.01m)^2? When I plugged the numbers into an online calc they also got 89.9N ... I also really enjoy all these videos + just want to make sure I'm not getting mixed up!
Always love your videos, helping me through Orgo, Physics II and MCAT prep. Thank you so much! You rock!
Great to hear that the videos are helping you, Chani - good luck with all your studies!
This guy absolutely loves Chris
Way to go Chris!
Chad's throat had a rough time today.
Thanks for your videos. Pretty sure calculation @ 5:40 should be 0.89 because the scientific notation comes out to be 8.9*10^-1

I see what you did there 😜
