The nucleus of a 125xe atom (an isotope of the element xenon with mass 125 u) is 6.0 fm in diameter. it has 54 protons and charge q=+54e(1 fm = 1 femtometer = 1×10−15m.) hint: treat the spherical nucleus as a point charge.

a) what is the electric force on a proton 9.0 fm from the surface of the nucleus?

express your answer in newtons.

b) what is the proton's acceleration?

express your answer in meters per second squared.

2) two 3.5-cm-diameter disks face each other, 2.0 mm apart. they are charged to ± 11 nc .

a) what is the electric field strength between the disks?

express your answer in newtons per coulomb.

b) a proton is shot from the negative disk toward the positive disk. what launch speed must the proton have to just barely reach the positive disk?

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
