(b) What charge must a 0.200 mg drop of paint have to arrive at the object with a speed of 10.0 m/s? Please answer in terms of C

Particle A has a charge of 10uC and a mass of 0.001kg. Particle A starts out at a speed of v = 1000m/s. At some time later, particle A has come to rest. What is the electric potential difference AV from where particle A started to where it stopped? Ignore gravity.

A proton (mass = 1.67 × 10-27 kg, charge = 1.60 × 10-19 C) moves from point A to point B under the influence of an electrostatic force only. At point A the proton moves with a speed of 50 km/s. At point B the speed of the proton is 92.9 km/s. Determine the potential difference VB -VA (in units of А volts). Select one: O A. 24.02 О в. 31.38 Ос. -50.38 O D. -31.99 O E. 2.12

One long wire carries current 40.0 A to the left along the x axis. A second long wire carries current 74.0 A to the right along the line (y = 0.280 m, z = 0). (a) Where in the plane of the two wires is the total magnetic field equal to zero? y = m (b) A particle with a charge of -2.00 μC is moving with a velocity of 1501 Mm/s along the line (y = 0.100 m, z = 0). Calculate the vector magnetic force acting on the particle. (Ignore relativistic effects.) F = N (c) A uniform electric field is applied to allow this particle to pass through this region undeflected. Calculate the required vector electric field. E = N/C

An electrostatic paint sprayer has a 0.200 m diameter metal sphere at a potential of 22.0 kV. (a) What charge is on the sphere? C(b) Paint droplets initially at rest are dispensed from a paint gun. These droplets are then repelled by the paint sprayer toward the object to be painted. This object is grounded and therefore the electric potential is taken to be zero everywhere on the object. What charge must a 0.600 mg drop of paint have to arrive at the grounded object with a speed of 17.0 m/s? C

Two identical balls each having a density pare suspended from a common point by two insulating strings of equal length. Both the balls have equal mass and charge. In equilibrium, each string makes an angle with the vertical. Now, both the balls are immersed in a liquid. As a result, the angle does not change. The density of liquid is o. Find the dielectric constant of the liquid.
