A0.2kg mass attached to the end of a spring is whirled in a vertical circle by a student. at some position, the mass experience a downward force of –62jn and a horizontal force 38i n. determine its acceleration in the position.

a=363.593m/s*2   we have rectangular component of force so we first find force resultant by square both component then square root and finally divide with 0.2 kg mass

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

true is the correct answer
