Ahollow sphere (of negligible thickness) with no load, with a radius of 8.00 cm, surrounds a charge of 20.00 μc located at the origin of a cartesian coordinate system. a 2.00 mm radius drill is aligned along the z axis and a hole is made on the surface of the sphere. calculate the electrical flow through the borehole.

a

39.3 n*m2/c

b

17.7 n*m2/c

c

587 n*m2/c

d

35.3 n*m2/c

e

353 n*m2/c

The electrical flow through the borehole is 353 Nm²/C.

(e) is correct option.

Explanation:

Given that,

Radius = 8.00 cm

Charge = 20.00 μC

radius of drill = 2.00 mm

We need to calculate the electrical flow through the borehole

Using formula of electric flow

Where, q = charge

R = radius of sphere

r = radius of drill

Put the value into the formula

Hence, The electrical flow through the borehole is 353 Nm²/C.
