A uniform electric field of 100 N/C points in the +x direction. Four positions are shown in the figure: a=(2, 0), b=(2, 1), c=(0, 1), and d=(-2, 0). (Units are in meters for (x, y) positions). The electric potential at positions a, b, c, and d are Va, Vb, Vc, and Vd, respectively. Which of the following statement is true? +y C ob + +X O a E O Va and Vd are the same O Vb is larger than Va O Vd is the largest O Vc and Vb are the same O Va is the largest Three circuits are shown in the figure. Each circuit consists of three identical capacitors (C1=C2=C3=1 F), and the same battery (V = 1 V). The charge stored in capacitor C1 is qla, q1b, and q1c, respectively. Which of the following statement is true? (a) ( b ) (c) C1,q1b q1a C1,q1c C2 C1 C2 C3 O q1b = qla + q1c O q1b=2 x qla + q1c O qla = 1/2 x q1b O q1c = 1/2 x q1b O qla = 1/2 x q1c
