How many light years would someone travel in 10 years if they traveled 6000 miles a week

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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
