Two balloons each have mass 4.0x10 kg. Balloon 1 has a negative net charge. Balloon 2 has twice the net negative charge of balloon 1. Balloon 1 is taped to the wall, and balloon 2 is tied to a string of length 0.70 m, which is attached to the ceiling directly above balloon 1 as shown. In the final equilibrium situation, the string makes a 20 degree angle away from balloon 1, and the two balloons are at the same...
Two balloons have equal and opposite charges. Balloon one has N= 106 excess electrons
Two balloons have equal and opposite charges. Balloon one has N= 106 excess electrons. The balloons are separated by d= 1.8 m and each electron has a negative charge of e = 1.602 * 10-19 C. Part (a) What is the charge on balloon two, Q2, in C? Part (b) What is the magnitude of the force in N) of balloon one on balloon two using the variables provided and the Coulomb constant k (k = 8.988 x 109 N m2/C2).

Two balloons are rubbed with a piece of wool and suspended by threads near each other, see figure below. (Assume the balloons are exactly the same as each other in terms of mass, size, and how vigorously they were rubbed). How will the balloons behave and explain your reasoning (be specific in terms of the angles the string will make)? 2) Repeat question 1, except the balloon on the left is now rubbed much more vigorously than the balloon on...

Question 1: (Total 25 marks. Each question is worth 5 marks each) For each of the statements below, indicate whether the statement is true or false and explain your reasoning A. Object A with a net charge of +5C is placed 1 cm away from Object B with a net charge of +8C. When Object A is moved a further 2 cm away from Object B, the size of the force between the two objects will increase. B. Two balloons...

Two balloons filled with air are each tied to very light 0.5-m-long strings. The loose ends of the strings are taped to the same position on a horizon tal bar. When both are equally rubbed with the same material they both develop a static charge and repel each other making an angle of 30° with respect to 2. the vertical. )With this experiment alone can you tell what type of charge is on the bal- loon? Explain. (b) Is this...

1. a- A spherical balloon made of rubber (an insulator) has the size of 2.00 m in radius. An amount of charge Q = –1.50×10–6 C is uniformly distributed on the balloon. What is the electric field E at the point 2.40 m from the center of the balloon (use positive sign if E points away from the center and negative sign if E points toward the center)? b- An infinitely large plane carries a uniformly distributed charge such that...
