Question

A simple pendulum is suspended from the roof
of a trolley which moves in a horizontal direction
with an acceleration a, then the time period is
given by T = 2???? √(???? / g) , where g is equal to
(a) g (b) g – a
(c) g + a (d) √(g² + a²)

Answer 1

option A) g is the right answer

Answer 2

Answer:

effective acceleration is √g2+ a2
