MHT CET Physics question
A stone of mass 'm' tied to a string of length 'l' is whirled in a circle of radius 'r' under the effect of gravity. If its radial acceleration is 'p' times the acceleration due to gravity (g) then its linear acceleration at a point on the circle, where the string becomes horizontal (P is +ve) [MHT-CET 2023, MHT-CET 2023]
Answer: (D)
Solution
The stone has radial acceleration pg and, with gravity acting tangentially at the horizontal position, the accelerations combine in quadrature, giving the form
