An object is in circular motion. how will the object behave if the centripetal force is removed

Aprotein molecule in an electrophoresis gel has a negative charge. the exact charge depends on the ph of the solution, but 30 excess electrons is typical. what is the magnitude of the electric force on a protein with this charge in a 1600n/c electric field? write in two significant numbers, and also in newton

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.
