An 8.75 kg point mass and a 14.0 kg point mass are held in place 50.0 cm apart. a particle of mass m is released from a point between the two masses 17.0 cm from the 8.75 kg mass along the lines connecting the two fixed masses.
a. find the magnitude (a) of the acceleration of the particle in m/s^2.
b. find the direction of the acceleration of the particle. either (i) the acceleration of the particle is toward the 8.75kg mass, or (ii) the acceleration of the particle is toward the 14.0kg mass.

Answer

given,

mass of the = m₁ = 8.75 Kg

another mass of the object = m₂ = 14 Kg

distance between them = 50 cm

R₁ = 17 cm

R₂ = 50 -17 = 33 cm

a) Force applied due to the Mass 8.75  in +ve x- direction

Force applied due to mass 14 Kg in -ve x-direction

net force

F = F₁ + F₂

Using newton second law

b) As the acceleration of mass comes out to be  +ve hence, the direction will be toward the mass of 8.75 Kg

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
