Question
**Problem Statement:** Two masses, \( m_1 = 2.0 \, \text{kg} \) and \( m_2 = 1.3 \, \text{kg} \), are connected by a light string, as shown. The blocks are static and the pulley is ideal. If \( \theta = \phi = 25^\circ \), what is the magnitude of the friction force (in N) acting on the block \( m_1 \)? **Diagram Description:** - The diagram illustrates two masses connected by a string over an ideal pulley. - Mass \( m_1 \) is positioned on an inclined plane, which forms an angle \( \theta \) with the horizontal. Here, \( \theta = 25^\circ \). - Mass \( m_2 \) is hanging vertically and is connected via a string over the pulley. - The angle between the string and the direction of the incline, denoted as \( \phi \), is also \( 25^\circ \). **Objective:** Calculate the friction force acting on \( m_1 \). The forces are balanced since the blocks are static.
