A moving particle encounters an external electric field that decreases its kinetic energy from 9140 eV to 5710 eV as the particle moves from position A to position B. The electric potential at A is -63.0 V, and that at B is +10.0 V. Determine the charge of the particle. Include the algebraic sign (+ or -) with your answer.
On planet Tehar, the free-fall acceleration is the same as that on Earth, but there is also a strong downward electric field that is uniform close to the planet's surface. A 1.98-kg ball having a charge of 5.22 ?C is thrown upward at a speed of 20.1 m/s. It hits the ground after an interval of 4.10 s. What is the potential difference between the starting point and the top point of the trajectory? (Use 9.8 m/s2 for the acceleration due to gravity.)
A small object with a mass of 270 μg carries a charge of 20.0 nC and is suspended by a thread between the vertical plates of a parallel-plate capacitor. The plates are separated by 5.00 cm.

Two objects collide head-on (see figure below). The first object is moving with an initial speed of v1i = 8.09 m/s and the second object is moving with an initial speed of v2i = 10.00 m/s. Assuming the collision is elastic, m1 = 5.06 kg, and m2 = 6.18 kg, determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations) v1f = m/s v2f = m/s
Q.8 Plates were fixed on the top and bottom of a cubical box with each side equal to 2 cm. A capacitor was constructed out of this box by filling it with a suitable dielectric material. In an experiment with this capacitor, the charge stored was measured and the electric field between the plates was determined as the charging potential difference was varied. The results are tabulated below. Charge stored/uC 7.5 30 60 75 90 Electric 0.5 2.0 4.0 5.0 6.0 field/Vcm-1 Plota suitable graphwhich can be used to determine the dielectric strength, and hence the capacitance of the capacitor used in this experiment. Calculate the total energy stored by the capacitor when the electric field is 400 V/m.

The Covid-19 virus is still a huge global problem. One way to ensure coverage and getting into corners. One must however ensure that the disinfectant being used can be charged. Air-assisted electrostatic disinfectant spraying has a device that charges and then repels disinfectant droplets onto objects that are grounded.
