b) 15F
c) 13F
d) 20F

Text Solution

Verified by Experts

The correct Answer is:
A, C
i. During the motion of bomb i9ts horizontal velocity u remains constant and is same as that of aeroplane at every point of its path.
Suppose the bomb explodes i.e. reaches the ground in the t
Distance travelled in horizontal direction by bomb = ut= the distance travelled by aeroplane.
So bomb explodes vertically below the aeroplane.
ii. Let teh aeroplane moves making angle theta with horizontal for both bomb and aeroplane.

Horizonta distance `= u cos theta t`
t= time for bomb to reach the ground.
So, in this case also, the bomb will explode vertically below the aeroplane.
