A0.650 kg air-track glider is attached to each end of the track by two coil springs. it takes a horizontal force of 0.900 n to displace the glider to a new equilibrium position, x= 0.070 m. find the effective spring constant of the system.

Spring constant will be 12.857 N/m

Explanation:

Horizontal force is given  F = 0.900 N

Displaced in position x = 0.070 m

We have to fond the spring constant

Displacing force is equal to , here K i spring constant

So spring constant

So effective spring constant will be 12.85 N /m

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
