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

The armature of a motor is accelerated uniformly from rest to a rotational velocity of 1800 rev/min in 10 seconds. the rotationa
Liono4ka [1.6K]
The initial angular velocity of the motor is zero, while the final angular velocity is 1800 rev/min. Let's convert this into rad/s, keeping in mind that
1 rev = 2 \pi rad
1 min = 60 s
we have
\omega_f = 1800  \frac{rev}{min}  \cdot  \frac{2 \pi rad/rev}{60 s/min}=188.4 rad/s

And so now we can calculate the angular acceleration of the motor:
\alpha =  \frac{\omega_f - \omega_i }{t} = \frac{188.4 rad/s -0}{10 s}=18.8 rad/s^2
