Step up transformer is a device which is used to step up the voltage which is input with some value.
This is based upon the principle of mutual inductance and in this the voltage input and voltage output is different because of number of turns.
Here if ideal transformer is given then power input and power output of the transformer must be same as there is no power loss in ideal transformer.
So we can write
here
= 73.37 A
= 4623 V
= 105033 A
now using above equation we will have
solving above we will have
For the cement bag we can say as per its force diagram we will have
here we will have
now we will have
now plug in all data
so the pulling force will be 295 N
