Question

For a uniform copper rod of length 50 cm and a diameter of 3 mm kept on a frictionless horizontal surface:

A. The rod will remain stationary
B. The rod will slide to the right
C. The rod will slide to the left
D. The rod will rotate around its axis

Answer 1

The uniform copper rod will remain stationary on a frictionless horizontal surface, as no external forces or torques are acting on it, in accordance with Newton's first law of motion.

Step-by-step explanation:

For a uniform copper rod of length 50 cm and a diameter of 3 mm kept on a frictionless horizontal surface, the behavior of the rod depends on external forces or torques applied to it. Given that no forces or movements are described:

• The rod will remain stationary, as per Newton's first law of motion, which states that an object at rest will stay at rest unless acted upon by an unbalanced external force.

Since no external forces are mentioned, and the surface is frictionless, implying no frictional resistance that could lead to motion, the copper rod will not undergo translational or rotational motion spontaneously.
