Explanation The three figures forms an equilateral triangle as shown below. Figure-(1) Write the expression to calculate the value of r . cos 30 ° = 15.0 cm r r = 15.0 cm cos 30 ° = 17.32 cm Consider the free body diagram of charge A. Figure-(2) Calculate the value of θ . sin θ = 17.32 cm 50 cm θ = sin − 1 ( 0.3 ) = 20.27 Calculate the forces. tan θ = F q m g F q = m g tan θ Substitute 20.07 ° for θ in the above equation. F q = m g tan ( 20.27 ° ) = 0.3693 m g (I) Consider the figure as shown below. Figure-(3) Calculate the forces. cos 30 ° = F q 2 F F q = 2 F cos 30 ° = 1.732 F (II) Write the expression for force acting on a charged particle. F q = k e q 2 r 2 Here, F q is the force acting on the charged particle, k e is the coulomb’s constant, q is the charge and r is the distance. Substitute ( k e q 2 r 2 ) for F in equation (II) to calculate F q

The de-excitation of a state occurs by competing emission and relaxation processes. If the relaxation mechanisms are very effective:a) the emission of radiation is largeb) the emission of radiation is smallc) the emission occurs at a shorter wavelengthd) the de-excitation occurs only by emission processes

m C A block of mass m slides down a ramp of height hand collides with an identical block that is initially at rest. The two blocks stick together and travel around a loop of radius R without losing contact with the track. Point A is at the top of the loop, point B is at the end of a horizon- tal diameter, and point C is at the bottom of the loop, as shown in the figure above. Assume that friction between the track and blocks is negligible. (a) The dots below represent the two connected blocks at points A, B, and C. Draw free-body dia- grams showing and labeling the forces (not com ponents) exerted on the blocks at each position. Draw the relative lengths of all vectors to reflect the relative magnitude of the forces. Point A Point B Point C (b) For each of the following, derive an expression in terms of m, h, R, and fundamental constants. i. The speed of moving block at the bottom of the ramp, just before it contacts the stationary block ii. The speed of the two blocks immediately…
