concentrated sulfuric acid is typically 18.1 M H2 SO4. Calculate the volume in mL of concentrated sulfuric acid needed to prepare 125 mL of a 0.100 M H2SO 4 solution
physics
Electric field at a distance r from a charge q is given by Coulomb's law: E = k q / r^2 To get the E-field, you have to add the contribution of 3 charges: E1 = k q1 / r1^2 E2 = k q2 / r2^2 E3 = k q3 / r3^2 You can look at the geometry and so simple addition and subtraction...
