Question
Physics Name makes Print Your B down on an electron la Find direction of force the the XX that produce magnetic field a in the wire would Find the of the current directed as shown. A proton moves perpendicular to a uniform magnetic five with a speed of 2 in the y2 and a force causing an acceleration of 1.2 x10 m/s m/s, experiences the tz direction. Determine the magnitude and direction when its velocity is direction of the field. a: 1.2 Y10 1.2 10 1.92 -27 3.2 to 2.0 x 1 Z direct o minimum horizontal rod is has a mass per unit length of 45 What is the magnetic field of and direction in the rod that can cause it to float in a horizontal its 1.2T pointing towards north?Explanation / Answer
1) Force acting will be in the left direction
2) F = qVB
ma = qVB
B = ma / qV
= 1.67*10^-27* 1.2*10^11 / 1.6*10^-19*2*10^5
= 0.0062625 T (in +x - direction)
