Answer:
h = 48.077 ft
Explanation:
given,
distance between two observer = 300 ft
angle of elevation to top pole = 16° and 20°
height of the flagpole = ?
now,
Let h be the height of the flagpole
Let x be the distance of the pole
now,
again applying
h = 48.077 ft

Explanation:
As we know that the force per unit length of two parallel current carrying wires is given as
here we know that
d = 2.2 cm
now from above equation we have
