Aparticle of mass m slides down, under gravity, a smooth ramp which is inclined at angle θ to the horizontal. at the bottom, it is joined smoothly to a similar ramp rising at the same angle θ to the horizontal to form a v-shaped surface. if the particle slides smoothly around the join, determine the period of oscillation, t, in terms of the initial horizontal displacement x from the centre join. note the shape of the potential well.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
