Given electric charge force What are the diameters of the disks?
Two identical closely spaced circular disks form a parallel-plate capacitor. Transferring 2.8×109 electrons from one disk to the other causes the electric field strength between them to be 1.7×105 N/C.
The equation for capacitance is:
C = ε*A/d
The electric field is:
E = V/d
V = E*d
The charge on a capacitor is:
Q = C*V = ( ε*A/d )*( E*d )
Note that the "d" (which represents plate separation distance) cancels.
Q = ε*A*E
A = π*r^2 = π*D^2/4 = Q/( ε*E )
where "D" represents the plate diameter.
D^2 = 4*Q/( π*ε*E )
D = sqrt( 4*Q/( π*ε*E ) = sqrt( 4*2.8*10^9*1.6*10^-19 / ( π* 8.854*10^-12 * 1.7*10^5 ) )
D = 19*10-^-3 m = 1.9 cm
