Question

this question is from the book Biomedical Applications ofIntroductory Physics by J. A. Tuszynski and J. M. Dixon. suppose the plasma membrane of a cell has a surface charge perunit area of about 10C/m2 on one side and an equal butopposite charge on the other side. estimate the electric feildstrength inside the plasma membrane. this question is from the book Biomedical Applications ofIntroductory Physics by J.

Explanation / Answer

Given   surface charge density   = 10 C/m2           Electric field strength E = / o                                             = (10 C /m2   ) / (8.85*10-12 )                                              = 0.118 *1013 N/C
