Question

an object is lifted off a table by use of a spring scale. What two forces are acting on the load

a. Weight and friction
b. Drag force and friction
c. Gravity and the force applied by the scale
d. The force of the scale and the force of the
block.

Answer 1

Answer: c. Gravity and the force applied by the scale

Explanation:

When the load is lifted, tow forces act on it, it weight acting downwards and the force applied by the scale in the upward direction. Since, it is lifted off the table, friction between table and object would act no more because friction is a contact force. The net force would be acting upwards and hence, the object is able to lift off. Thus, the correct option is c. Gravity and the force applied by the scale.

Answer 2

Answer:

C. Gravity and the force applied by the scale

This is because whenever you are lifting something up gravity is the force going against you and the spring scale is the force going with you.
