Question

If the magnitude of displacement is numerically equal to
that of acceleration, then the time period is
(a) 1 second (b) π second
(c) 2π second (d) 4π second

Answer 1

✪ Question

If the magnitude of displacement is numerically equal to  that of acceleration, then the time period is

(a) 1 second (b) π second

(c) 2π second (d) 4π second

✪ Solution

(c) 2π seconds

✪ Explanation

ÿ = ω²y

⇒ω = 1

⇒4π²/T² = 1

⇒T² = 4π²

⇒T = 2π seconds

Answer 2

$\large\underline\bold{ANSWER \red{\huge{\checkmark}}}$

$\huge{\underline\bold{OPTION:- C\:\: \huge{\red{\checkmark}}}}$

ÿ = ω²y

⇒ω = 1

⇒4π²/T² = 1

⇒T² = 4π²

⇒T = 2π seconds
