Two projectile protons \( P_1 \) and \( P_2 \), both with spin up (along the \( +z \)-direction), are scattered from another fixed target proton \( T \) with spin up at rest in the \( xy \)-plane, as shown in the figure. They scatter one at a time. The nuclear interaction potential between both the projectiles and the target proton is \( \hat{\lambda} \vec{L} \cdot \vec{S} \), where \( \vec{L} \) is the orbital angular momentum of the system with respect to the target, \( \vec{S} \) is the spin angular momentum of the system, and \( \lambda \) is a negative constant in appropriate units. Which one of the following is correct?

Read the following passage and answer the questions:
Young children’s engagement with print and the importance of good literature cannot be undermined. Children’s meaningful engagement with reading can be initiated and strengthened by providing them with opportunities to read books according to their age, context and interests. When children enter school, a good collection of literature in their classroom shall convey that reading is valued an essential component of the process in the classroom. It should offer a space that is inviting and engaging into a world of interesting pictures, stories, books and other reading material. For teachers a reading corner in the classroom gives a platform where they can support and facilitate children to make meaning while reading. Teachers can transform the physical space of the classroom to create a conducive, lively and inviting space.
