Question

The two ends of a 40 cm long chain are
fixed at the same height as shown in
figure. The string makes 45° angle with
the vertical at the two supports. Find
the radius of curvature (in cm) at the
lowest point.​

Answer 1

Answer:

Explanation:

i think it can be solved using projectile

here range = 40cm

u^2sin2theta/g = 40

u=20cm/s

find hmax

u^2sin^2 theta /g

400*1/2 / 10

20cm

Answer 2

Explanation:

The two ends of a 40 cm long chain are fixed at the same height as shown in figure. The string makes 45° angle with the vertical at the two supports. here range = 40cm

$u^2sin2/g = 40$

u=20cm/s

find hmax

$u^2sin^2 theta /g$

400*1/2 / 10

20cm
