Question

CD Balloon mass m d Two balloons are hanging as shown in the figure. The angle - 10.0000 degrees. The distance between the balloons d=0.2000m. The mass of each balloon is m-0.0005kg. Find the magnitude of charge on each balloon (assuming the same amount of charge) Give your answer in MicroCoulombs.

Answer 1

Answer: Teose 92 Tsine ANTED d2 d mg considera the charge on cal Depulsive topce on to the presence System is each balloon is q. For thig anelectpi- is acted each chapged ballon due of the charge of other ballon . consider in equiliboium. T is tension in the string. the From figure we can write : mg = Teose 1 92 4TEO d2 Tsine Dividing equation (2) by equation (1) tge get tano = 92 ATTEO made q= 4ITEo mad? tane Given, m= 0.0005 kg d = 0.2 m = 100 So, q= = 1417x8.864x10 12 * 0.0005 % 9,8% (0-2)?x tan 100 96.2 x 10-8 > y = 0.062 Mc Therefore the charge on each balloon 18 a = 0.062 rec.
