An object with a charge of -2.9 μC and a mass of 4.6×10−2 kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight.

A. Find the magnitude of the electric field.

B. Find the direction of the electric field.

C. If the electric charge on the object is doubled while its mass remains the same, find the magnitude of its acceleration.

D. If the electric charge on the object is doubled while its mass remains the same, find the direction of its acceleration.

Expert Solution

The positive sign shows that the acceleration is in the direction of electric force. Since the direction of electrostatic force is upwards, hence the direction of acceleration is upwards.

Therefore, the direction of acceleration of the object is upwards

If the mass of the charge is very small (mass = 2.9×10^-25kg) so that its weight (weight in Newtons = mass in kg × 9.8 m/s2) is negligible compared to the electric force, what is the magnitude of its acceleration? Recall Newton's 2nd Law. the magnitude of the electric force is 27.68×10^−17? Write your result in terms of 10^9 m/s2. For example, if the result is 1.234 ×10^9 m/s2, just enter 1.234 (keep 3 decimal places).
