Question 1 of 5

A constant force F is applied to a relativistic particle of rest mass m. If the particle starts from rest at t = 0, its speed after a time t is -

A

$c\left(I-e^{-\frac{F t}{m c}}\right)$

B

$c \tan h\left(\frac{F t}{m}\right)$

C

$\frac{F t c}{\sqrt{m^{2} c^{2}+F^{2} t^{2}}}$

D

$\frac{F t}{m}$
