Calculate the speed of ions pass underflected through crossed E and B fields for which E=7.7kv/m and B=0.14T

To calculate the speed of ions that pass undeflected through crossed electric and magnetic field, we can use the following formula:

v = E / (B * q)

Where:
v: velocity of the ions
E: electric field strength
B: magnetic field strength
q: charge of the ion

Given:
E = 7.7 kV/m = 7.7 * 10^3 V/m
B = 0.14 T
We need to determine the charge of the ion (q) in order to calculate the velocity (v).

Once we know the charge of the ion, we can substitute the given values into the formula to find the velocity of the ions.
