Answer:
Electric field,
Explanation:
It is given that,
Mass of sphere, m = 2.1 g = 0.0021 kg
Charge,
We need to find the magnitude of electric field that balances the weight of a plastic spheres. So,
a = g
or
Hence, the magnitude of electric field that balances its weight is . Hence, this is the required solution.
