Parallel combination

Explanation:

There are two types of combination of resistances.

1. Series circuit :When the resistances are connected back to back, the combination is called series combination. Here, the current in each resistance is same. The effective resistance is given by

R = R' + R''

2. Parallel combination: When the one ends of all the resistances connected at a point and the other end is connected at other point, the combination is said to be parallel. Here, the voltage difference is same for all the resistances.

The effective resistance is given by

So, to get the effective resistance is small, we have to connect the resistances in parallel combination.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

i don't know that i agree with that but what's the question ?
