I only need question number 2 thank you !!!

A=29 B=39 C=139 D=12 There are an electron and a proton with distance r between each particle as shown. . 604 Take r = B cm. Take charge of electron and proton magnitude as 1.609 x 10 -19C and Coulomb P te constant as k= 8.99 x109 Nm2/C2 a) Calculate net Electric field at point P, the middle between particles, what is the direction? (10 points) b) Calculate net Electric potential at P, does it have a direction? (10 points) 2. Consider the following circuits. a) Calculate equivalent capacitance between a-b terminal if C1=C2=B/2 UF, C3 = B UF (10 points) a b b) Calculate equivalent resistance between a-b terminal, If R=D(10Points) c) Write the Kirchhoff's potential difference rule for left and right loops by drawing your chosen current directions and loop directions. Use given symbols (10 points) RI R2 R3 - 82
