Answer:
19 cm
Explanation:
inner radius, a = 16 cm, C = 113 p F = 113 x 10^-12 F
Let b cm be the radius of outer sphere.
The formula of capacitance of spherical capacitor is given by
C = 4π∈0 a b / (b - a)
a b / ( b - a) = C / 4π∈0
a b / ( b - a ) = 113 x 10^-12 x 9 x 10^9
a b / ( b - a ) = 1.017
16 x 10^-2 x b x 10^-2 = 1.017( b - 16) x 10^-2
0.16 b = 1.017 b - 16.272
0.857 b = 16.272
b = 19 cm
7.59Ns
Given parameters:
Force = 1360N
Time of contact = 5.85 x 10⁻³s
Unknown:
Impulse = ?
Solution:
The impulse of the ball is given as:
Impulse = Force x time
Impulse = 1360 x 5.85 x 10⁻³ = 7.59Ns
