A Charged ball is inside a very long tube, in which an electricfield can beswitched on and off. This electric field accelerates the ball 1(0.5 kg) with a constantacceleration. The electric field of the tube is switched on for 1 𝑠so that the ball isaccelerated and fired into the air (from ground 𝑦 = 0 𝑚). The ball1 would reach aheight of H which would be the highest point. Directly after theelectric field isswitched off a canon that is distance = 3 m away from the tubefires a cannon ball (the angle with horizontal is 45°), the initial speed of thecannonball is unknown. Thecannon ball has a mass of 𝑚 . The cannonball should hit the ball 1at 𝑐𝑎𝑛𝑛𝑜𝑛𝑏𝑎𝑙𝑙 = 50𝑘𝑔the highest point H. The colour of both the balls are blue and itis a sunny Sundaymorning. Calculate :● Force of the electric Field that has to be applied to fulfil theconditions.● Hint: It is possible to define the time when the E-Field isswitched off to be𝑡 = 0 𝑠{Assume there is no friction, air drag and gravity =9. 8 𝑚/𝑠 }2
