please consider sin and cos value for the first one.

In figure below, three identical point charges q, are fixed in the xy plane. Calculate both (a) the electrical potential V and (b)the electrical filed E at the organ O. A point charge +q is a distance d/2 directly above the center of a square of side d. what is the electric Flux through the square? Two large metal plates of area 1.0 m2 face each other. They are 5.0 cm apart and have equal but opposite charge on their inner surfaces. Using a voltmeter, a 6 V potential difference is measured between the two plates calculate (a) the corresponding capacitance of the two plates, (b) the magnitude of the charge of the charge on each plate, and (c) the electric field between the plates. You man neglect any edge effects during analysis.

Explanation / Answer

Q1)We know that potential is a scalar function.so potential

V=(KQ1/R1)+ (KQ2/R2)+(KQ3/R3),K=9 x 109 S.I

=>V=2.707(Kq/d)

=>E=0.646(Kq/d2) (-i)^ +(-j)^

Q2) answer is Q/6?0

Q3) A) CAPACITANCE
