Question

Problem: A table tennis ball has a positive charge of 7.0 × 10-8 coulombs. It experiences an electric force of 3.6 × 10-4 newtons at a point slightly above a positively charged table. Calculate the magnitude of the electric field at this point. Part A: Enter the variable for the quantity you need to find. Use your keyboard and the keypad to enter your answer. Then click Done.

Answer 1

The electric field is measured in newtons/coulomb.  So
$\frac{3.6 \times 10^-^4 N}{7.0 \times 10^-^8C}= 5142.86 \frac{N}{C}$
