Question

Please answer the following in detail

Answer 1

Answer:

• Coefficient of Friction: 0.1

• Force applied on the block: 15 N

• Gravity = 10 m/s²

• Acceleration = ?

Let's calculate the maximum force exerted by Friction.

Friction = Coefficient of Friction × Normal

⇒ F = μN

⇒ F = 0.1 × 5 kg × 10 m/s²

⇒ F = 5 N

Therefore Frictional Force is 5 N.

Net Force acting on the block is calculated by subtracting friction from the applied force, as friction plays an opposing role here.

Therefore Net Force is given as:

⇒ Applied Force - Frictional Force

⇒ 15 N - 5 N

⇒ 10 N

According to Newton's Second law,

Force = Mass × Acceleration

⇒ 10 N = 5 kg × Acceleration

⇒ Acceleration = 10 N / 5 kg

⇒ Acceleration = 2 m/s²

Therefore Acceleration of the block is 2 m/s².

Hence Option (B) is correct
