please my exam is very near after somedays ,so please solve alll all questions i need your help .please i will give you a like please help me
A beam of protons enters a uniform 0.01 T magnetic field normal to the beam's velocity. If the mass of the proton is 1.67x10-27 kg, then the period (in us) of rotation of a proton in its circular path is: a) π b) 2π c) 3п d) 4π e) 5π Ja ma Q9: A proton (qp, mp) and an a-particle (qa-2qp. ma-4mp) have the same speed (v) enter a region of uniform magnetic field pointing into the plane of the page as shown in the figure. If the radius of the proton's circular path is rp, then the radius of the a-particle's circular path is q (A) Ta Tp (B) Ta Tp/4 (C) Ta Tp/2 (D) Ta=41p Q5: A proton and electron have the same speed (v) and enter a region of uniform magnetic field pointing into the plane of the page as shown in the figure. If the radius of the electron's path re 0.4 cm then the radius of the proton's path r, (in cm) is: (Note: m/m 1833) (A) 183.3 (B) 366.6 (C) 550 T. Hasan Abdulla Salman Q15) The electric field (E) and the magnetic field (B) in a velocity selector are uniform and perpendicular to each others. A single ion of charge (Q) and mass (m) enters the velocity selector and pass it without any deflection. Which one of the following statement is true? Q m A) The acceleration of the ion in the velocity selector is (QE/m). B) The speed of the ion in the velocity selector is (E/B). C) The speed of the ion in the velocity selector is zero. D) The acceleration of the ion in the velocity selector is (QyB/m). (OP Abo Salman me Mp (D) 733.2 58 Ⓒ Ⓒ (E) Ta=21p .... Ⓡ Ⓡ Ⓡ Ⓒ Ⓡ Edown (C) 1.43 (E) 916.5 11 Ⓡ B B V
