Question

A body of mass 2 kg is at rest on a horizontal table. The coefficient of friction between the body and the table is 0.3. A force of 5 N is applied on the body. The acceleration of the body is –

• A. 0 m s^–2
• B. 2.5 m s^–2
• C. 5 m s^–2
• D. 7.5 m s^–2

Answer 1

Answer: (A)

0 m s^–2

Answer 2

$2 \mathrm {~kg} \longrightarrow \mathrm { F } = 5 \mathrm {~N}$

µ = 0.3

friction f = µ mg = 0.3 × 2 × 10 = 6 N, acce = 0
