Question:
What is the tension in the string when the ball hangs straight down at rest?
A ball with a net charge of +450 nC and mass 0.75 g is suspended from a thread of length 12 cm in a uniform electric field of 8.0 kV/m downward. Do not ignore gravity. The system acts like a pendulum but with a downward electric force added to the gravitational force.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
