a.
The orientation of the magnetic field and the electric field for a proton.
a.
Explanation of Solution
Introduction:
Under a magnetic field the direction of force on a moving charge is determined by Fleming’s right hand rule. In an electric field, the direction of force is collinear with the direction depending upon the charge.
In accordance with Fleming’s right-hand rule, if the thumb is directed towards the movement of the positive charge and middle finger points in the direction of the force pushing the charge, then the index finger points in the direction of the magnetic field.
Thus, as the protons (same as direction of current) move in a clockwise direction, to move them in a circular path, the magnetic field must point up at right angle to the velocity of the protons.
The electric field should be in a clockwise direction similar to the motion of the protons.
Conclusion:
As the protons move in a clockwise direction, to move them in a circular path the magnetic field must point up at a right angle to the velocity of the protons.
The electric field should be in a clockwise direction similar to the motion of the protons.

In accordance with the Fleming’s right-hand rule,when the thumb is directed towards the movement of the positive charge and middle finger points towards the force pushing the charge, then the index finger points in the direction of the magnetic field.
Hence as the antiprotons are negatively charged move in an anticlockwise direction, to move them in a circular path the magnetic field must point up at a right angle to the velocity of the protons.
Conclusion:
Hence, as the antiprotons are negatively charged, they move in an anticlockwise direction.To move them in a circular path the magnetic field, must point up at a right angle to the velocity of the protons.

Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…arrow_forward
