Calculate the mechanical advantage of a pulley system if only 10 lb is required to lift a 500 lb block

As we know that mechanical advantage is defined as the ratio of output force and input force for the pulley system

Here we know that it required 10 lb of input force in order to lift the block of 500 lb so here output force is 500 lb

now we have

here we have

now from above formula we have

so mechanical advantage of this system is 50

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.
