    Basic Question about Forces: Understanding Normal and Reaction Forces

    1. Okay so in a book it says that a normal force is the force a surface exerts on an object so there can be no net charge when the object is at rest (correct me if i am wrong). But when setting up a problem i found in a book, specifically Oman's "How to Solve Physics Problems" they gave me this...
