A body of mass \( 0.5 \mathrm{~kg} \) experience a force \( F=(2+ \)
\( \mathrm{P} \) \( 3 x^{2} \) ) N where \( x \) (in metre) is the displacement from

W origin. It is released to move along \( x \)-axis from origin then its initial acceleration is
(1) \( 2 \mathrm{~m} / \mathrm{s}^{2} \)
(2) \( 10 \mathrm{~m} / \mathrm{s}^{2} \)
(3) \( 4 \mathrm{~m} / \mathrm{s}^{2} \)
(4) Zero
