I assume you are asking "what is the magnitude of the force experienced by a particle with charge -6.2C at this spot". The magnitude of the force on a particle with charge q due to an electric field of magnitude E is simply the product: |q*E...

Simply F = q * E I get F = 3.4e6 N to two significant digits. Now if you meant -8.0 µC, then F = 3.4 N Hope this helps!

A) t = 800m / 1.6m/s = 500 s B) d = 0.9m/s * 500s = 450 m C) t = d / (V1 - V2) = 450m / 0.7 m/s = 643 s D) Θ = arctan(0.9/1.6) = 29º

The acceleration is the same regardless of the direction. But we do have to change 11.0 km/h to m/s: 11.0 km/h(1000m/km)(1h/3600s) = 3.0556m/s The formula for centripetal force: F = mv^2/r F = ma a = F/m = v^2/r a = 3.0556^2/16.0 = 0.5835m/s^2
