Answer:
v = 0.999981c m/s
Explanation:
Using the time dilation equation
T = stationary time = 100 years
T₀ = 11/12 years = 0.917 years
v = speed of travel in the space = ?
c = speed of light = 3 * 10⁸ m/s
v = 299987395.57 m/s
v = 2.99 * 10⁸ m/s
v = 0.999981c m/s
Answer:
given,
radius of rod = 5 cm
charge per unit length (λ) = 30.0 n C/m = 30 × 10⁻⁹ C/m
electric field duel to long straight wire =
a) distance = 3 + 5 = 8 cm
= 18 × 10⁹
E = 6750 N/C
b) distance = 10 + 5 = 15 cm
= 18 × 10⁹
E = 3600 N/C
c) distance = 100 + 5 = 105 cm
= 18 × 10⁹
E =514.28 N/C
