the following data apply to the speaker system:(adsbygoogle = window.adsbygoogle || []).push({});

coil diameter = 5.8cm

coil turns = 86

coil and cone mass = 30g

magnetic flux density = 0.12T

Current in the coil = 1.8A

Using the above data, the acceleration of the cone will be?

A) 12.6 b) 79.3 c) 113 d) 247

This comes from my revision sheet i dunno how number of turns related to this

30/1000 x a = 1.8 x 0.12 x 2pi x 5.8/100 x 86

a = 113 (SOLVED THX!)
