A negatively charged (-121 uC) block is sitting on a frictionless, flat surface. This 12 kg block is attached to a vertical wall with a horizontal, 0.39 m long string that is under a tension of 100 N. Embedded in the wall (on the other side of the string) is another charge. What is the charge of this embedded charge in the wall? Assume that the block is stuck in place.

Types of Charge Carriers

A carrier is a type of object which carries a particular thing from one point to another point. For instance, people use different vehicles from one place to another, and the vehicle carries those people and acts as a carrier.

Question

A negatively charged (-121 uC) block is sitting on a
frictionless, flat surface. This 12 kg block is attached to a
vertical wall with a horizontal, 0.39 m long string that is
under a tension of 100 N. Embedded in the wall (on
the other side of the string) is another charge. What is
the charge of this embedded charge in the wall?
Assume that the block is stuck in place.
