Two charges q1 and q2=4q1 are seperated by a distance r. The forceon q1 due to q2 F12=F, then the force on q2 due to q1 is
a 1/4 F
b 1/16 F
c 4F
d 8F
e F
f none of these

I think its either e or f

the mass of the glider (m) and the effective spring constant (k).With a balance you measure the mass of the glider to be m = 0.253kg. [We ignore the mass of the springs]

0.4293 0.212
0.4677 0.434
0.5062 0.657
0.5445 0.879

1. Use linear least squares to find the slope of this force vs.position data. From this slope, calculate the effective springconstant k:
N/M
2. Calculate the natural frequency fF you should expect for thismechanical oscillator:
Hz
