Few qustions: 1.A point charge of 1,5 μC experiences an electric force of 0,08 N. What is the magnitude of electric field at that point.
2.Find the electric potential of a charge q=3x10–7 C, at distances away from its position of 18 cm in units of V. (Take k=9x109 Nm2/C2)
3.The points A and B are at distances away from a charge, q=10 μC of 2 cm and 1 cm, respectively. Find the potential difference between these points (Uab). (Take k=9x109 Nm2/C2)
4.A 100-W light bulb is connected to a 220-V source and operates for 4 hours. Find the current passing through the light bulb.
