NOT HOME WORK QUESTION (itsfrom last year exam question) 1. The problem statement, all variables and given/known data electric field between two disk of radius of R and at distance D=a/2 is given by the following n=charge density (Q/A) E_0= the constant 8.85*10^-12 E=(n/E_o)((1- (a/2)/(((a/2)^2)+(R^2))^1/2 for what value of the ratio of the plate radius to separation between the plates does the electric field at point x=a/2 deffer by 1percent from the result n/E_o for infinite sheets? R/a=...... 2. Relevant equations the equation for infinite sheet is E=n/2E_o 3. The attempt at a solution not sure how to approach this question is it R/2a=0.01 then R/2a*0.01=50? please can some one explain this to me!!
