A 0.1 m by 0.1 m sheet of cardboard is placed in a uniform electric field of 10 N/C. At first, the plane of the sheet is oriente
Eduardwww [97]

Answer:

The angle is 89°.

Explanation:

Given that,

Electric field = 10 N/C

Electric flux = 0.01 N-m²/C

Area A=\pi\times(0.1)^2

We need to calculate the angle

Using formula of electric flux

\phi=EA\cos\theta

\cos\theta=\dfrac{\phi}{EA}

Where, E = electric field

\phi = electric flux

A = area

Put the value into the formula

\cos\theta=\dfrac{\dfrac{0.01}{2}}{10\times\pi\times(0.1)^2}

\theta=\cos^{-1}(0.01592)

\theta=89.0^{\circ}

Hence, The angle is 89°.
