What is the value of the electric field at the surface of the cylinder surrounding the charged filament?
The electric field at the surface of the cylinder is 51428V/m. Given the length of the charge (l) is 7m, the charge (q) is 2μC, and the radius of the cylinder (r) is 10 cm, we can use the formula E=2kλ/r to calculate the electric field. By substituting the values, we get E = (2×9×10^9 N⋅m^2/C^2 × 2×10^−6 C) / (0.1m × 7m) = 51428 V/m.
Electric Field Calculation for Charged Filament and Cylinder
An electric charge is the property of matter where it has more or fewer electrons than protons in its atoms. Electrons carry a negative charge, and protons carry a positive charge. When an object has more protons than electrons, it becomes positively charged, and when it has more electrons, it becomes negatively charged.
In the given scenario, we have a uniformly charged filament with a length of 7m and a total positive charge of 2.00μC. The filament is surrounded by an uncharged cardboard cylinder with a length of 2.00 cm and a radius of 10.0 cm.
To calculate the electric field at the surface of the cylinder, we can make a reasonable approximation by treating the filament as an infinite line of charge due to its large length compared to the cylinder. The formula to calculate the electric field is E=2kλ/r, where λ is the linear charge density.
By substituting the given values into the formula, we get E = (2 × 9 × 10^9 N⋅m^2/C^2 × 2 × 10^−6 C) / (0.1m × 7m) = 51428 V/m. This calculation gives us the electric field at the surface of the cylinder surrounding the charged filament.
Understanding the concept of electric charge is essential in physics, as it explains the interactions between charged particles and the forces they exert on each other. By studying the properties of charge, scientists have developed theories and laws to describe these phenomena accurately.
By understanding how to calculate the electric field in scenarios like the one described above, we can gain insights into the behavior of charged particles and the forces they generate in a given system.
