Question

which diagram best shows forces acting on an object that is sitting at rest on a table? a b c d

Explanation:

Step1: Identify forces on resting object

An object at rest on a table has two main forces acting on it: gravitational force (weight) pulling downwards and normal force exerted by the table upwards. These two forces are equal in magnitude and opposite in direction for the object to be in equilibrium.

Step2: Analyze each option

• Option A: Has a downward - acting gravitational force and an upward - acting normal force of equal length, representing the balanced forces on the object at rest.
• Option B: Has two downward - acting forces, which is incorrect as there is no such situation for an object at rest on a table in the absence of other external forces.
• Option C: Has two upward - acting forces, which is incorrect as the gravitational force acts downwards.
• Option D: Has horizontal forces, which are not present for an object simply resting on a table without any horizontal pushes or pulls.

Answer:

A.
