Field Theory

if two equal charges , each of 1c,were separated in air by a distance of 1km,what would be the force between them?

Field Theory

An electric charge q caused an electric potential of V = -218 V at point A 10.6 m from q. What is the electric charge q?

Field Theory

A cargo was dropped down a helicopter which hovered at height of h=125m

When will the cargo reach the land?free fall acceleration is g=10m/s2.Air resistance must be ignored

Field Theory

On a surface of a planet, 60 J of work is done against gravity to raise a mass of 2.0kg through a height of 10m. Determine the gravitational field strength g on this planet

Field Theory

The Sun has a radius of 6.9599× 10 8 m. Use the mass of the Sun from your data

booklet to calculate the gravitational field strength at the surface of the Sun.

(274 N/kg)

Field Theory

A particle with the same charge as an electron experiences a force of 5.2 × 10-12N and traveling at a speed of 4.21 × 107m/s at right angles to a magnetic field. a. How strong is the magnetic field? b. What does its acceleration if its mass is 1.88 × 10-28 kg?

Field Theory

starting from rest, a train is uniformly accelerated and reaches a velocity of 20km/h after 15cesconds. what is its acceleration

Field Theory

Motion along a frictionless inclined plane

Field Theory

A 100 μF capacitor is charged from a supply of 1000V, disconnected from the supply and then connected across an uncharged 50 μF capacitor.

Calculate the energy stored initially and finally in the

two capacitors. What conclusion do you draw from a

comparison of these results?
