A block weighing 15N rests on a flat surface and a horizontal force of 3N is exerted on it. Determine the friction force on the block

Yeah, the correct answer is Option C

Weight of the block = 15 N (which means its mass is about 15 ÷ 9.8 ≈ 1.53 kg — but we won’t need that here)

Horizontal force applied = 3 N

The surface is flat, and no coefficient of friction (μ) is given.

Now, since 𝙣𝙤 𝙢𝙤𝙩𝙞𝙤𝙣 is mentioned, and the block is just 𝙧𝙚𝙨𝙩𝙞𝙣𝙜, it means:


"The friction force = the applied force", as long as it doesn’t 𝙚𝙭𝙘𝙚𝙚𝙙 the maximum static friction.

So, frictional force = 3N
