Problem 68

How close must two electrons be if the electric force betweenthem is equal to the weight of either at the Earths surface?

Step-by-Step Solution:

Step 1 of 3

Continuous Distribution of charges Two methods: •Method #1: Divide the distribut+on + E into infinitesimal elements dE an+ + integrate to get the full electric field + •Method #2: If there is some special dq symmetry of the distribution, usE = k ˆ Gauss’ Law to derive the field from r2 46 Simple cases  Infinitely long charged rod E kλ 1 λ r E r2 = r 2π 0 Infinitely large charged plate Constant! 2
