A block of mass 1 kg is pulled up on an inclined plane 60° by a force of 10 N. Coefficient of friction is µ = 0.1. Find the magnitude of Work done by the friction by the time block moves up by 10 m.
Multiple Choice Options
- A 5 × 10⁻² J
- B 5 J
- C 5000 J
- D 500 J
Step-by-Step Verified Solution
W_friction = μmg cos 60° × 10 => W_friction = 0.1 × 1 × 10 × 0.5 × 10 => W_friction = 5 J
