Answer:
t₀ = 1.55 s
Explanation:
According to Einstein's Theory of Relativity, when an object moves with a speed comparable to speed of light, the time interval measured for the event, by an observer in motion relative to the event is not the same as measured by an observer at rest.
It is given as:
t = t₀/[√(1 - v²/c²)]
where,
t = time measured by astronaut in motion = 3.1 s
t₀ = time required according to observer on earth = ?
v = relative velocity = 0.87 c
c = speed of light
3.1 s = t₀/[√(1 - 0.87²c²/c²)]
(3.1 s)(0.5) = t₀
<u>t₀ = 1.55 s</u>
The angle subtended by the arc of movement of both chambers is the same. Thus:
S = r∅, for chamber A:
2.3 x 10² = 3.2 x 10² ∅
∅ = 0.72 rad
∅ is the same for B so:
S = 1.1 x 10³ x 0.72
S = 7.92 x 10² m
