Questions & Step-by-Step Solutions
If a charge of +3μC is placed in an electric field of 1000 N/C, what is the force acting on it?
Step 1: Identify the charge (q) given in the problem. It is +3μC (microcoulombs).
Step 2: Convert the charge from microcoulombs to coulombs. 1μC = 10^-6 C, so +3μC = 3 × 10^-6 C.
Step 3: Identify the electric field (E) given in the problem. It is 1000 N/C (newtons per coulomb).
Step 4: Use the formula for force (F) in an electric field, which is F = q * E.
Step 5: Substitute the values into the formula: F = (3 × 10^-6 C) * (1000 N/C).
Step 6: Calculate the force: F = 3 × 10^-3 N.
Step 7: Convert the force to a more understandable unit if needed. 3 × 10^-3 N is equal to 0.003 N or 3 mN (millinewtons).
Electric Force Calculation – The question tests the ability to calculate the force acting on a charge in an electric field using the formula F = q * E.
Unit Conversion – Understanding the conversion of microcoulombs (μC) to coulombs (C) is essential for accurate calculations.
