Q.A 100 g ball on a 60 cm long string is swung in a vertical circle about a point 200 cm above the floor. The string suddenly breaks when it is parallel to the ground and the ball is moving upward. The ball reaches a height of 600 cm above the floor. What was the tension in the string an instant before it broke?

Q. A electron is accelerated from rest by a potential difference of 350 V. It then enters a uniform magnetic field of magnitude 200 mT with its velocity perpendicular to the field. Calculate
(a) the speed of the electron?
(b) the radius of its path in the magnetic field?
