A body takes n times as much time to slide down a 45^ rough incline as it takes to slide down a smooth 45^ incline. The coefficient of friction between the body and the incline will be

Options

  1. A1 1-n²
  2. B1- 1 n²
  3. C1 1-n²
  4. D1- 1 n²

Correct answer

B. 1- 1 n²

Step-by-step solution

The coefficient of friction, Here, aligned &= (1- 1 n² ) &=45^ aligned = 45^ (1- 1 n² )=1- 1 n²
