The body of mass 400 g slides on a rough horizontal surface. If the frictional force is 3.0 N, find a. the angle made by the contact force on the body with the vertical and b. the magnitude of the contact force. Take `g=10 m/s^2`

Text Solution

AI Generated Solution

To solve the problem, we need to find two things: 1. The angle made by the contact force with the vertical. 2. The magnitude of the contact force. Let's go through the solution step by step. ### Step 1: Calculate the weight of the body The weight of the body (W) can be calculated using the formula: ...
