A beam of protons is moving in the x direction with a speed of 10.6 km/s through a region in which the electric field is perpend

nataly862011 [7]

Answer:

E= 8501.2

Explanation:

Given Data;

Speed = 10.6 km/s = 10.6*10^3 m/s

Magnitude = 0.802 T

The magnitude of the electric field is calculated using the formula;

q E = q v B

E = v B

= 10.6 *10^3 * 0.802

= 8501.2

The direction of the electric field will point along the negative z-axis

A marble is thrown horizontally with a speed of 7 m/s. When the marble lands, it hastraveled a horizontal displacement of 30 m.

Alex Ar [27]

Answer:

t = 4.28 s

Explanation:

The horizontal speed of a marble = 7 m/s

The horizontal displacement covered by the marble = 30 m

We need to find the time for which the marble is in air. Let the time is t. Using the formula for speed to find it as follows :

$s=\dfrac{d}{t}\\\\t=\dfrac{d}{s}\\\\t=\dfrac{30\ m}{7\ m/s}\\\\=4.28\ s$

So, it will in the air for 4.28 s.
