A short 10-g string is used to pull a 50-g toy across a frictionless horizontal surface.If a 3.0 * 10^-2 N force is applied horizontally to the free end of the string, the force of the string on the toy, at the other end, is: A)0.15 N B)6.0 * 10^-3 N C)2.5 *10^-2 N D)3.0*10^-2 N E)3.5* 10^-2 N

Question

Quizplus · Accepted Answer

The force on the toy is calculated by considering the tension in the string and the mass of the toy. The tension in the string is the same as the applied force, but the force on the toy is reduced due to the mass of the string. The correct force is 2.5 x 10^-2 N.
