Thanks man, that helps

E1= (9x10^9)(10x10^-6)/(5)^2 (dont know where/if too include the negative values in this) = 3600 E2= (9x10^9)(30x10^-6)/(5)^2 =10800 =14400

Hello, any answers appreciated: 'Two spheres are 5 m apart. Sphere 1 has a charge of -20 mC and sphere two has a charge of -50 mC. (a) Find the strength of the electric field at the sphere's halfway point. (b) Find the electric potential at the halfway point
