1. State the law of universal gravitation (b) The force of attraction between the sun and the earth is
3.84 × 102N and their distance apart is 1.4 × 1012m. If the mass of the sun is 1.89 × 1030Kg, determine the
mass of the earth (c) Two objects of masses 90kg and 100kg are separated by a distance of 1m. Calculate
the magnitude of the force of attraction between them (G = 6.6 × 10−11Nm2Kg−2)
2. State Coulomb’s law of electrostatic attraction (b) A charge of 2 × 10−5C experiences a force of 80N in a
uniform electric field. Calculate the magnitude of the electric field intensity
3. Two parallel plates at a distance of 9 × 10−3𝑚 apart are maintained at a p.d of 700V. Calculate the electric
field strength between them (b) Two capacitors each of capacitance 2𝜇𝐹 are connected in parallel. If the p.?
