MCQ
A $500 \,kg$ car takes a round turn of radius $50 \,m$ with a velocity of $36 \,km/hr$. The centripetal force is .......... $N$
- A$250$
- B$750$
- ✓$1000$
- D$1200$
✓
Answer
Correct option: C.
$1000$
c
(c)$v = 36\frac{{km}}{h} = 10\frac{m}{s}$
(c)$v = 36\frac{{km}}{h} = 10\frac{m}{s}$
$F = \frac{{m{v^2}}}{r} = \frac{{500 \times 100}}{{50}} = 1000\,N.$
