Two spherical point charges each carrying a charge of 40 μC are attached to the two ends of a spring of length 20 cm. If its spring constant is 120 Nm-1 , what is the length of the spring when the charges are in equilibrium?

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.
