A 15-loop circular coil 22 cm in diameter lies in the xy plane. The current in each loop of the coil is 7.6 A clockwise, and an external magnetic field B⃗ =(0.55i^+0.60j^−0.65k^)T passes through the coil.

part A Determine the x, y, and z projections of the magnetic moment of the coil, μ⃗ . Express your answers using two significant figures separated by commas.

part B Determine the x, y, and z projections of the torque on the coil due to the external magnetic field. Express your answers using two significant figures separated by commas. Part C Determine the potential energy U of the coil in the field (take U =0 at θ = π/2). Express your answer to two significant figures and include the appropriate units.

where is the circuit diagram ?

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
