What is the acceleration of a proton moving with a speed of 7.7 m/s at right angles to a magnetic field of 1.9 T

iris [78.8K]

Answer:

The acceleration of the proton is 1.403 x 10⁹ m/s²

Explanation:

Given;

speed of proton, v = 7.7 m/s

magnitude of magnetic field, B = 1.9 T

Magnetic force of moving proton is given by;

F = qvBsinθ

Centripetal force on the moving proton is given by;

$F = m(\frac{v^2}{r})\\\\F = m(a_c) \\\\a_c \ is \ the \ centripetal \ acceleration$

$qvBsin\theta = ma_c\\\\ac = \frac{qvBsin(90)}{m}$

where;

q is charge of the proton = 1.602 x 10⁻¹⁹ C

m is mass of proton = 1.67 x 10⁻²⁷ kg

$ac = \frac{(1.602*10^{-19})(7.7)(1.9)sin(90)}{1.67*10^{-27}}\\\\a_c = 1.403*10^{9} \ m/s^2$

Therefore, the acceleration of the proton is 1.403 x 10⁹ m/s²

A charge of −8.3 μC is traveling at a speed of 7.4 × 106 m/s in a region of space where there is a magnetic field. The angle bet

solniwko [45]

Answer:

The magnitude of the magnetic field is $1.1\times 10^{-4}\, T$

Explanation:

Given charge q = −8.3 μC

speed of charge $v=7.4\times 10^{6}\, \frac{m}{s}$

Angle between magnetic field and the velocity of charge $\Theta =52^{\circ}$

Strength of magnetic force on charge $F=5.4\times 10^{6}\, N$

Let magnitude of magnetic field be B

Since the magnetic force on a free moving charge in the magnetic field given by

$F=\left |q\vec{v}\times \vec{B}\right |=\left | qvBsin\Theta\right |$

=> $5.4\times 10^{-3}=\left | -8.3\times 10^{-6}\times 7.4\times 10^{6}\times sin(52^{\circ})\times B \right |$

=> $B=1.1\times 10^{-4}\, T$

Thus the magnitude of the magnetic field is $1.1\times 10^{-4}\, T$

In a vacuum the speed of light is 300000000 m/s. If light slows

madreJ [45]

Answer:

n = 1.5

Explanation:

The speed of light in vacuum is 300000000 m/s

The speed of light in glass is 200000000 m/s

We need to find the refractive index of the glass.

We know that, the ratio of speed of light in vacuum to the speed of light in medium is equal to refractive index of the medium.

$n=\dfrac{300000000 }{200000000 }\\\\=1.5$

So, the refractive index of the glass is 1.5.
