Answer:
f = [ 1/ 2L] √ [ T /u]
u is the mass per unit length.
u = 0.008 kg / 5m= 0.0016 kg/m
T/u = 39.24 / 0.0016 =24525
√ [ T /u] = 156.61
f = [ 1/ 2L] √ [ T /u] = [1/ 2*5 ] *156.61
f = 15.66 Hz
Explanation:
It is given that,
Length of the poster, l = 0.95 m
Breadth of the poster, b = 1 m
The poster is in the shape of rectangle. For a rectangular shape, perimeter is equal to :
P = 2(l+b)
P=2(0.95+1)
P=3.9 m
(b) One digits, P = 4 m
(c) Two digits, P = 3.9 m
(d) Three digits, P = 3.90 m
