Question

Show that , if A/B is an integer and A is a prime number then A=B , when B don't equal to 0/1​

Answer 1

Answer:

Given ,

L = 49 cm

l = 51 cm - 49 c = 2 cm

Cross sectional area = 20 mm^{2}mm

2

= 0.2 cm^{2}cm

,

mass (m) = 100 g , R = 51 cm

ω = 40 r.p.s = 80 π rad·sec^{- 1}sec

−1

When the mass attached to the string is whirled, the length of the string increases under the effect of centrifugal force.

The centrifugal force, F = mRω^{2}ω

2

= 100 x 51 x (80 π)^{2}(80π)
