Explanation:
In a magnetic field, the radius of the charged particle is as follows.
r =
where, m = mass, v = velocity
q = charge, B = magnetic field
Therefore, q will be calculated as follows.
q =
=
=
=
= +2e
Thus, we can conclude that the charge of the ionized atom is +2e.
Answer:
Velocity, u = 14.7 m/s
Explanation:
It is given that, a driver can probably survive an acceleration of 50 g that lasts for less than 30 ms, but in a crash with a 50 g acceleration lasting longer than 30 ms, a driver is unlikely to survive.
Let v is the highest speed that the car could have had such that the driver survived. Using a = -50 g and t = 30 ms
Using first equation of kinematics as :
In case of crash the final speed of the driver is, v = 0
u = 14.7 m/s
So, the highest speed that the car could have had such that the driver survived is 14.7 m/s. Hence, this is the required solution.
