3-2.Motion in Plane
easy
An electron is moving in a circle of radius $2 \,m$ with speed $4 \,m / s$ Find the acceleration of the electron. (in $m / s ^{2}$)
A$8$
B$4$
C$16$
D$10$
(AIIMS-2019)
Solution
The acceleration of the electron can be calculated as,
$a=\frac{v^{2}}{r}$
$=\frac{(4)^{2}}{2}$
$=8 m / s ^{2}$
$a=\frac{v^{2}}{r}$
$=\frac{(4)^{2}}{2}$
$=8 m / s ^{2}$
