Question
Circle the answer A uniform magnetic field points out of the page. The diagram shows the instantaneous velocities of a proton (p), an electron (e), and an alpha-particle (alpha, He^2+ ion). The magnetic force on the proton points The magnetic force on the electron points The magnetic force on the alpha-particle points Fill the blank A uniform magnetic field points out of the page shown. Three particles shot into the region curve as shown. For each particle, indicate whether it has negative (-), zero (0), or positive (+) electric charge: particle a: _______ particle b: _______ particle c: _______ Solve the following problem A fluorine ion (q = +4e, m = 3.15 times 10^-26 kg) that was accelerated through a potential difference of 48.0 kV moves in circular motion in a uniform 0.850-tesla magnetic field, see diagram. The diagram shows the correct direction of its motion. Calculate the speed of the fluorine ion. Calculate the radius of its cyclotron orbit.Explanation / Answer
the Magnetic force is perpendicular to the plane of magnetic field and velocity.
if it is a + charge use right hand if negative use left hand,
a)Always remember this method
For proton use right hand move ur fingers in the direction of the motion or velocity of proton now turn your hand in such a way that you can curl your finger in the direction of the magnetic force the thumb upward is our magnetic force direction
Answer (a)
B)same now use left hand for the negative charge move fingers in the direction of electron motion and curl them in the direction of the magnetic field again the force is acting upwards
Answer (a)
C) alpha is positive charge use right hand again move fingers upward motion turn your hand toward you i.e palm towards so you can curl fingers in the direction of the magnetic field force is towards right given by thumb direction
Answer (d)
