| **How will the body move if the resultant of these forces is constant in magnitude, and in the direction it always remains perpendicular to the speed of the body?**

If the resultant of all forces is constant in magnitude and in direction all the time remains perpendicular to the speed of movement of the body, then the body is moving in a circle.

The speed of the body is always directed tangentially to the trajectory of motion.

When moving in a circle, the body has a centripetal acceleration, which is directed along the radius of curvature, that is, perpendicular to the speed.

The resultant of all forces is directed just like the acceleration, along the radius and perpendicular to the speed.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
