Electric field in a region is given as $E = (10 - 5 x) \hat{i}$ . A charge particle of mass 5 kg and charge $Q (= 1 C)$ is situated at origin and free to move in given electric field. Then choose the correct options (Neglect gravity)

Options:(select one or more)

Answer:

A, B, C, D

Solution:

$F = qE = 10 - 5 x$ ; equilibrium at $x = 2$ where $F = 0$

$F = - 5 (x - 2)$ : SHM about $x = 2$ with $ω = \frac{5}{5} = 1$ rad/s, so motion is oscillatory. (A) correct

Released from origin, amplitude $= 2$ m, so maximum displacement from origin $= 4$ m. (B) correct

$v_{ma x} = ω A = 2$ m/s at the mean position $x = 2$ . (C), (D) correct

Answer: (A), (B), (C), (D)
