Question

Statement 1: $v=u+at$ can be used as an equation for SHM.
Statement 2: Acceleration in SHM is variable.

• A. Statement 1 is true, statement 2 is false
• B. Statement 1 is false, statement 2 is true
• C. Statement 1 and statement 2 are true
• D. Statement 1 and statement 2 are false

Answer 1

The correct option is B Statement 1 is false, statement 2 is true

A particle executing simple harmonic motion has acceleration given by,
$a=-{\omega }^{2}x$
Where $a$ is variable i.e. it is a function of $x$.
In $v=u+at,a$ is necessarily be a constant.
$\therefore v=u+at$ cannot be used as an equation for SHM.
