Chapter 29: Q. 61 (page 833)

An antiproton (same properties as a proton except that $q = - e$ ) is moving in the combined electric and magnetic fields of FIGURE. What are the magnitude and direction of the antiproton’s acceleration at this instant?

Short Answer

Expert verified

Acceleration, $a = 2.4 \times 10^{10} m / s^{2}$ upward

Step by step solution

Magnetic attraction (part a)

Due to the electrical field $E$ , the electrical force $F_{E}$ is exerted on the charge, and it's given by

$F_{E} = q E$

Because antiproton charge is negative, the electrical field exerts an electrical force during a downward direction.

Equation of magnetic attraction,

$F_{B} = q v B$

Magnetic attraction (part b)

The magnetism is exerted upward within the wrong way of the electrical field force, In keeping with the right hand rule. As a result, the antiproton is subjected to the web force of the $2$ forces.

$F_{net} = F_{B} - F_{E}$

$m a$ $= q v B - q E$

$a = \frac{q (v B - E)}{m}$

Finalization

Put the values in equation

$a = \frac{q (v B - E)}{m}$

$= \frac{1.6 \times 10^{- 19} C ((500 m / s) (2.5 T) - 1000 V / m)}{1.67 \times 10^{- 27} kg}$

$= 2.4 \times 10^{10} m / s^{2}$

The antiproton goes within the direction of the magnetic pull because the acceleration is positive. As a result, the acceleration is upward.
