Question

explain the magnitude and effect of centripetal force

Answer 1

centripetal force is the force on an object on a circular path that keeps the object moving on the path. It is always directed towards the centre and its magnitude is constant, based on the mass of the object, it's tangential velocity, and the distance of the object from the centre of the circular path

Answer 2

‘magnitude’, from Latin ‘magnus’=’big’, is a fancy word for ‘size’, “how big something is”. The magnitude of a geometric vector is its length; the magnitude of a physical vector quantity, e.g. a force or an acceleration, is its size, just how big/strong/fast etc. it is, regardless of its direction and sense.
