Three charges q1 = 8 uC, q2 =3 uC , and q3 = -2 uC. Particle 1 from particle 2 has a distance of 0.06 m and particle 2 to particle 3 is separated by a distance of 0.04 m. a) Calculate the resultant force on q2. b) Solve for its direction.

Two charged spheres, q1= -2.00 x 10 -5 C and q2 = -1.50 x 10 -5 C are 0.1 m apart. Calculate the force that each charge exerts on the third charge, q3 = 5.00 x 10 -6 C which is 0.06 m away from q2.

Two identical small metal coated spheres R and S are given identical charges of 40nC each. They are suspended at the same point from a ceiling by means of identical light inextesible insulating threads of equal length.the threads are of negligible mass. When the system is in equilibrium the angle between the threads is 60° while the distance between R and S is 5 cm. Calculate the mass of sphere R

A pendulum consists of a small spherical mass suspended from a rigid
support by a length of thread of negligible mass.
The mass is swinging from side to side with an amplitude of 0.05 m and
a period of 1.40 s.
The motion of the mass can be considered to be simple harmonic.
Calculate the maximum acceleration of the mass.
