Answer:

The magnitude of the displacement is 6.00 m.

Explanation:

Given that,

Radius = 3.00 m

Displacement :

The displacement is the shortest distance between initial and final points,

We need to calculate the magnitude of the displacement

Using formula of displacement

d=2r

Put the value into the formula

d=2\times3.00

d=6.00\ m

Hence, The magnitude of the displacement is 6.00 m.

Consider a 2.54-cm-diameter power line for which the potential difference from the ground, 19.6 m below, to the power line is 11
tiny-mole [99]

Answer:

The line charge density is 1.59\times10^{-4}\ C/m

Explanation:

Given that,

Diameter = 2.54 cm

Distance = 19.6 m

Potential difference = 115 kV

We need to calculate the line charge density

Using formula of potential difference

V=EA

V=\dfrac{\lambda}{2\pi\epsilon_{0}r}\times\pi r^2

\lambda=\dfrac{V\times2\epsilon_{0}}{r}

Where, r = radius

V = potential difference

Put the value into the formula

\lambda=\dfrac{115\times10^{3}\times2\times8.8\times10^{-12}}{1.27\times10^{-2}}

\lambda=1.59\times10^{-4}\ C/m

Hence, The line charge density is 1.59\times10^{-4}\ C/m
