A particle begins at the origin and moves successively in the following manner as shown, 1 unit to the right, 1/2 unit up, 1/4 unit to the right, 1/8 unit down, 1/16 unit to the right etc. The length of each move is half the length of the previous move and movement continues in the ‘zigzag’ manner indefinitely. The co-ordinates of the point to which the ‘zigzag’ converges is –

The greatest possible number of points of intersections of 8 straight line and 4 circles is :
The number point of intersection between two circles can be counted by finding the number of ways in which one circle and one line can be selected out of the lot multiplied by 2 as one circle and one line can intersect at most two points.
For selecting r objects from n objects can be done by using the formula as follows
As mentioned in the question, we have to find the total number of intersection points.
For calculating the points of intersection between two lines, we can use the formula which is mentioned in the hint as follows =
For calculating the points of intersection between two circles, we can use the formula which is mentioned in the hint as follows =
For calculating the points of intersection between one line and one circle, we can use the formula which is mentioned in the hint as follows =
Hence, the total number of points of intersection is = 28 + 64 + 12 = 104

A force–time graph for a linear motion is shown in figure where the segments are circular. The linear momentum gained between zero and is
As the area above the time axis is numerically equal to area below the time axis therefore net momentum gained by body will be zero because momentum is a vector quantity
