Pathfinder Solution || Chapter 2 Newton's Laws of Motion || Q7 (Multiple choice question)

Welcome to our Advanced Problems Series. The problem discussed is as mentioned below. Problem no.7 (Chapter 2) Section: Multiple choice question Topic: Newton's laws of motion A small metal ball is being pulled gradually on a fixed frictionless hemisphere as shown in the figure. Radii of the ball and that of the pulley are much smaller than that of the hemisphere. As the ball slides from the bottom to a position close to the top of the hemisphere, how do the magnitudes of pulling force F and contact force R between the ball and the hemisphere change? (a) F increases and R decreases. (b) F decreases and R increases. (c) F decreases and R remains unchanged. (d) F remains unchanged and R decreases. Problem is solved by triangle law of vector addition. #iitjee #jeeadvanced #physicsproblems #physics #mechanics #physicsolympiad For all viewers, if you find any problem or any concept needs to be discussed, I will be glad to do so.
