yes. Thanks to anyone who spent time helping me out. I really appericiate it. :smile:

so in this example r is equal to 6 right

so would r be 6 or -1 in that case.

so 113=1X10^2 + 1X10^1 + 3X10^0 so in this case r also = 10. but how doe 14r +52r + 3r = 113r? im sorry for asking so many questions, but my prof literraly doent speak english and to top it off he stutters for about 5 sec on every word. and to top that off he's in his 80s.

ok then what would the r be in the above problem

how do i find the radix r of equalities. for example how would i find the radix r of 14r + 52r +3r =113r note:::: the r is a little subscribt on the bottom.

charge im assuming the charge is positive

oh wait I think I just got it. correct me if I am wrong please. if a charge enters a uniform electric field and it moves from point A to point B. The work done to move it from point Ato B=FD(distance moved), and if the charge moved towards the Low PE. it gained kinetic energy therefore it lost...

wow im still confused. I don't understand. This is the first topic in physics so far that has me confused.

Can some please explain the difference between "Electric potential Energy & electric potential" and when a problem is asking you to find the potential difference which is it asking for?
