Final answer:
To calculate the force on a 1.0 nC charge, the electric field strength must be known to apply the formula F = qE. Without the electric field strength given, the exact magnitude of the force cannot be determined.
Step-by-step explanation:
The student is asking for the magnitude of the force on a charge of 1.0 nC (nanocoulombs). To find this, the formula F = qE is used, where F is the force, q is the charge, and E is the electric field strength. Although the electric field strength is not given in the question, this formula is key to finding the force if the electric field strength is known. A similar example given is the force on a -0.250 µC charge in an electric field of 7.20 × 10^5 N/C, which results in a force of 0.180 N.
For the 1 nC charge mentioned in the student's question, the charge value would be 1.0 × 10^-9 C (1 nC is equal to 1.0 × 10^-9 coulombs), but without the electric field strength, the precise magnitude of the force cannot be calculated.
