1. Charges of magnitude 𝟏𝟎𝟎𝝁𝑪 each are located in vacuum at the corners A, B and C of an equilateral triangle measuring 4m on each side. If the charge at A and C are positive and the charge B negative, What it the magnitude and direction of the total force on the charge at C?
2. What is the magnitude of a point charge that would create an electric field of 𝟏.𝟎𝟎𝑵/𝑪 at points 𝟏.𝟎𝟎𝒎 away?
3. Consider a point charge +q placed at the origin and another point charge -2q placed at a distance of 9m from the charge +q. Determine the point between the two charges at which electric potential is zero.
4. An object having a net charge of 𝟐𝟒𝝁𝑪 is placed in a uniform electric field of 610N/C directed vertically. What is the mass of this object if it floats in the field?
5. What will be the electric field at a distance of 𝟑𝟎𝒄𝒎 from a 𝟑𝝁𝑪 point charge.
6. The electric field at a point due to a point charge is 𝟐𝟔𝑵/𝑪 and the electric potential at that point is 𝟏𝟑𝑱/𝑪. Calculate the distance of the point from the charge.
7. The electric field at a point 𝟎.𝟓𝒎 from a charge is 𝟐.𝟓𝑵𝑪^(−𝟏). Find the value of electric potential at that point.
