In Rutherford's famous scattering experiments that led to the planetary model of the atom, alpha particles (having charges of +2e and masses of 6.64 ✕ 10−27 kg) were fired toward a gold nucleus with charge +79e. An alpha particle, initially very far from the gold nucleus, is fired at 2.96 ✕ 107 m/s directly toward the nucleus, as in the figure below. How close does the alpha particle get to the gold nucleus before turning around? Assume the gold nucleus...
A metal sphere with charge q1-+8.60 nc is attached to the left-hand end of a nonconducting rod of length L-2.70 m. A second sphere with charge 2- +2.10 nc is fixed to the right-hand end of the rod (see figure below). At what position d along the rod can a charged bead be placed for the bead to be in equilibrium? d=2.06 x Your response differs from the correct answer by more than 10%. Double check your calculations. m Need...
A positive charge Q1 =+ 117 nC with mass M = 17 mg is released form rest at a distance r 1 = 6 mm from a fixed positive charge Q2=+ 311 nC, the speed of Q1 when it is at r2= 30 mm from Q2 is close to (in m/s): O 13.67 O 45.89 O 21.87 105.41 O 71.27
Two identical spheres each having charge Q =-11 nC and mass mOF 10 milligrams are held fixed at their positions 5.0 cm apart. A particle with charge q-+1.0 nC and mass mo-0.40 milligrams is released from rest at a position 5.0 cm from each sphere (so initially the particle and the spheres form an equilateral triangle). Find the speed of the positively charged particle when it passes a point exactly in between the two spheres. (k - 9.0 x 109...
