A stick of 1 m is moving with velocity of \(2.7 \times 10^{8} \, m \, s^{-1}\) . What is the apparent length of the stick \(\left(c = 3 \times 10^{8} \, m s^{-1}\right)\)
Text Solution
Verified by ExpertsThe correct answer is:
C
\(l = l_0 \sqrt{1 - \frac{v^2}{c^2}}\) \(= l_1 \sqrt{1 - \left(\frac{2.7 \times 10^8}{3 \times 10^8}\right)^2} \implies l = 0.44\,m\)
