A raindrop inside a thundercloud has charge

A raindrop inside a thundercloud has charge - $8 e$. What is the electric force on the raindrop if the electric field at its location (due to other charges in the cloud) has magnitude $2.0 \times 10^{6} \mathrm{N} / \mathrm{C}$ and is directed upward?

Key Concepts

Electric Charge

Electric charge is a fundamental property of matter that determines how particles interact via electromagnetic forces. It can be positive or negative, and its magnitude affects the strength of these interactions. The sign of the charge plays an important role in determining the direction of the force experienced when placed in an electric field.

Electric Field

An electric field is a vector field surrounding electric charges that represents the force per unit charge at each point in space. It is defined in newtons per coulomb (N/C) and provides both magnitude and direction, which determines how a charged particle will be influenced and accelerates within the field.

Force on a Charge in an Electric Field

The electric force experienced by a charge in an electric field is given by the equation F = qE, where q is the charge and E is the electric field. This relation implies that the magnitude of the force is directly proportional to both the charge and the field strength, while the sign of the charge determines the direction of the force relative to the field.
