Electric field intensity, e can be defined as the electric (coulomb) force on a unit test (1c) charge. find the electric field intensity at a distance, d from the center of a +q charged proton. use k as coulombe constant.

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3

According to newton’s first law of motion, which force is expected to cause a body to accelerate?
