Question

If a stone of mass 0.25kg tied to a string executes uniform circular motion with speed of 2m/s of radius 3m,what is the magnitude of tension force acting on the stone p?

Answer 1

Tension would be = mv²/r
= 0.25×2×2/3
=1/3= 0.33 N

Thanks for asking

Answer 2

Answer:

0.333 N

Explanation:

m=0.25kg

r=3m

v=2m/s

formula:

$f cp = mv^2 \r$

$1 \4 \times 2^2 \div 3 = 0.333n$
