Question
A. The solution to a problem is represented by the following equation:
(9.0×109Nm2/C2)(0.020C)(0.050C)/(100m)2+(9.0×109Nm2/C2)(0.010C)(0.050C)/(50m)2=(10kg)ax.
Suggest a situation that the equation might represent and formulate a problem for which it is a solution.
B. An alpha particle consists of two protons and two neutrons together in one nucleus with a mass of 6.64×1027 kg and charge +2e . The alpha particle flies at 3.0×106 m/s from a large distance toward the nucleus of a stationary gold atom (charge +79e ). e=1.6×1019C,k=9×109Nm2/C2.
Explanation / Answer
there is a charge of 0.050C on which force is applied by two charge 0.020C and ) 0.010C.
it is possible when all three charge in straight line on x axis or Y axis but in question it is mention that it is in X axis because we are finding ax.
so cosider 0.050C in right most postion and 0.010C is 50m left of 0.50C and 0.020C is left most at 100m from right most
