Question

If the velocity of the rod having the length 100 cm is 3 x 103 m/secthen what is the
length contraction for the given velocity
0.001 m
0.001 cm
0.01 m
0.01 cm​

Answer 1

Answer:

0.001m

Explanation:

Given,

Length = 100cm

Velocity = 3000m/s

We know length contraction formula.

$l = l \sqrt{1 - \binom{v}{c} } {}^{2}$

we put the value

l= 1 √1-3000^2/c^2

l= 1√1-9000000/9*10^16

l= 1√2999999/9*10^16

l= 1√3*10^-11

l= 1*5.5*10^-7

l= 5.5*10^-7

l= 0.001m Approximately

I try to help I don't know is it right or wrong but it's very complicated and interesting

I hope it's helpful to you

Answer 2

Answer:

Given,

Length = 100cm

Velocity = 3000m/s

We know length contraction formula.

l = l \sqrt{1 - \binom{v}{c} } {}^{2}l=l

1−(

c

v

2

we put the value

l= 1 √1-3000^2/c^2

l= 1√1-9000000/9*10^16

l= 1√2999999/9*10^16

l= 1√3*10^-11

l= 1*5.5*10^-7

l= 5.5*10^-7

l= 0.001m Approximately
