A solid sphere of radius 0.5 m is uniformly charged with a charge density of 1.127×10-8 C/m3. If the chosen Gaussian sphere has a radius of 0.2 m, determine the total electric flux through the Gaussian sphere.

Determine the capacitance of a conducting sphere with radius a surrounded by a thick conducting spherical shell with inner radius b and outer radius c. (Hint: you first might want to draw the charge distribution. Then consider where the "ground" of your capacitor is). 4π€ 00 a 4π€ 4πE。 b 4πE In(b/a) b

The figure below shows two charged particles separated by a distance of d = 1.50 cm. The charges are ₁ = -15.5 nC and 92 = 26.5 nC. Point B is at the midpoint between the two charges, and point A is at the peak of an equilateral triangle, with each side of length d, as shown. (Assume the zero of electric potential is at infinity.) d d A 60.0⁰ B d (a) What is the electric potential (in kV) at point A? kV (b) What is the electric potential (in kV) at point B? kV

please show the step clearly thank you
