Question 1
A long, straight wire carries a current and maintains a linear charge density of 6.0 μC/m. Find the electric field at a point 15 cm from the wire.
💡 Hint: Substitute the values in the formula directly.
Question 2
A uniformly charged disk has a surface charge density of 5 μC/m². Calculate the electric field at points (1) just above the disk's surface and (2) at a point far away from the disk.
💡 Hint: Use the respective formulas for different distances—directly substitute charge density.
