Problem
In a certain experiment to measure the ratio of charge to mass of elementary particles, a surprising result was obtained in which two particles moved in such a way that the distance between them always remained constant. It was also noticed that this two-particle system was isolated from all other particles and no force was acting on this system except the force between these two masses. After careful observation followed by intensive calculation, it was deduced that velocity of these two particles was always opposite in direction and magnitude of velocity was 103 ms−1 and 2×103 ms−1 for first and second particle, respectively, and masses of these particles were 2×10−30 kg and 10−30 kg, respectively. Distance between them were 12A˚ (1A˚=10−10 m). Acceleration of the second particle was
(1) 5×1015 ms−2
(2) 4×1016 ms−2
(3) 2×1016 ms−2
(4) zero
