A wave has angular velocity 12 rad/sec and maximum displacement X cm (X= last two digit [1] of your student’s ID). Calculate the maximum acceleration of the wave.

Explanation:

Given that,

The angular velocity of a wave,

The maximum displacement of the wave, A = 10 cm (let)

The maximum acceleration of the wave is given by :

Put all the values,

So, the maximum acceleration of the wave is equal to .

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
