A 63.2 kg climber finds herself dragling over the edge of a cliff. She’s connected by a rope of negligible mass to a rock located 48.6 m from the edge of the cliff, and help is on the way. However, it will be 36.5 s before help arrives, and the ice is frictionless. How massive must the rock be if she’s to be saved?

c) up is the direction the magnetic force is acting on the charge.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
