Question

$A space p a r t i c l e space i s space m o v i n g space i n space a space c i r c l e space w i t h space u n i f o r m space s p e e d space v. space space I n space m o v i n g space f r o m space a space p o i n t space t o space a n o t h e r space d i a m e t r i c a l l y space o p p o s i t e space p o i n t$

$T h e m o m e n t u m c h a n g e s b y m v$
$T h e m o m e n t u m c h a n g e s b y 2 m v$
$T h e k i n e t i c e n e r g y c h a n g e s b y (1 / 2) m v^{2}$
$T h e k i n e t i c e n e r g y c h a n g e s b y m v^{2}$

The correct answer is: $T h e space m o m e n t u m space c h a n g e s space b y space 2 m v$

$M o m e n t u m space c h a n g e s space b y space 2 m v space b u t space k i n e t i c space e n e r g y space r e m a i n s space s a m e.$
