Imagine that a relativistic train travels past your lecture room at a speed of 0.894 c. The passengers of the train claim that w

Lady bird [3.3K]

Answer:

The length of the train in the frame of the lecture room is 40.59 m.

Explanation:

Given that,

Speed = 0.894 c

Original length = 90.6 m

We need to calculate the length of the train in the frame of the lecture room

Using formula of length contraction

$L=L_{0}\sqrt{1-(\dfrac{v}{c})^2}$

Where, $L_{0}$ =original length

v = speed of train

Put the value into the formula

$L=90.6\sqrt{1-(\dfrac{0.894c}{c})^2}$

$L=90.6\sqrt{1-0.894^2}$

$L=40.59\ m$

Hence, The length of the train in the frame of the lecture room is 40.59 m.

Two protons are moving up when they enter a magnetic field that points towards you. What happens to the motion of the particles?

Llana [10]

The protons will possess a force pointing to the right.

The force is called Laurentz Force, which is measured by: F = qvB

Here, q is positive for proton, v and B are cross product determined by right hand rule.
