The velocity at which relativistic length of a body reduces to half or its proper length is ____?

جس رفتار سے جسم کی نسبت پسندانہ لمبائی آدھی رہ جاتی ہے یا اس کی مناسب لمبائی ____ ہوتی ہے؟

Answer: v = √3/2c

The relativistic length contraction formula is:

L = L₀√(1 - v²/c²)

Given L = L₀/2:

L₀/2 = L₀√(1 - v²/c²)

1/2 = √(1 - v²/c²)

1/4 = 1 - v²/c²

v²/c² = 3/4

v = √(3/4) * c = √3/2 * c

The answer is v = √3/2c.
