A beam of protons is directed in a straight line along the positive zz ‑direction through a region of space in which there are c

Zinaida [17]

Answer:

The magnitude is $B = \frac{450}{7.9* 10^5}$

The direction is the positive x axis

Explanation:

From the question we are told that

The electric field is E = 450 V/m in the negative y ‑direction

The speed of the proton is $v= 7.9* 10^5\ m/s$ in the positive z direction

Generally the overall force acting on the proton is mathematical represented as

$F_E = q(\vec E + \vec v * \vec B)$

Now for the beam of protons to continue un-deflected along its straight-line trajectory then $F_E =0$

So

$0 = q( E (-y) + v(z) * \vec B)$

=> $E\^y = v \^ z * \vec B$

Generally from unit vector cross product vector multiplication

$\^ z \ * \ \^ x = \^ y$

So the direction of B (magnetic field must be in the positive x -axis )

So

$E\^y = v \^ z * B\^ x$

=> $E\^y = vB ( \^ z * \^ x)$

=> $E\^y = vB ( \^y)$

=> $E = vB$

=> $B = \frac{450}{7.9* 10^5}$

=> $B = 0.0005696 \ T$

The velocity v of a particle moving in the xy plane is given by v = (6.0t -4.0t2 )i + 8.5j, in m/s. Here v is in m/s and t (for

atroni [7]

Answer:

Explanation:

Given

Velocity of the particle in vector form is given by

$v=\left ( 6t-4t^2\right )\hat{i}+8.5\hat{j}$

acceleration is rate of change of velocity thus acceleration is

$a=\frac{\mathrm{d} v}{\mathrm{d} t}$

$a=(6-8t)\hat{i}+0\hat{j}$

at $t=3\ s$

$a=6-8\times 3$

$a=-18\ m/s^2$
