The magnetic flux that passes through one turn of a 8-turn coil of wire changes to 4.5 Wb from 10.0 Wb in a time of 0.096 s. The average induced current in the coil is 265 A. What is the resistance of the wire

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

the ima (higher than 1m) will be greater than the ima with the height of 1m.
