उत्तर
- Definition: Gravitational force is a natural force that pulls two objects toward each other. It's the reason why objects fall to the ground on Earth and why planets orbit around the Sun.
- How it Works: The larger the mass of an object, the stronger its gravitational pull. That’s why Earth’s gravity is stronger than the gravity of a small object like a pebble.
- Examples: The force that keeps us from floating into space, The reason planets stay in orbit around the Sun.
- Importance: Gravitational force is essential for maintaining the structure of the universe. Without it, everything would drift apart!

They won’t eat peas, don’t like your bread -
For something in it crunches;
They gag on fat, the gravy’s gross,
They won’t eat grapes in bunches.
Tomatoes, onions, peppers, fish
Garlic nor cottage cheese;
Oh, it’s a dish uncommon rare
That truly seems to please.
No red sauce may the ice cream have,
“It’s bleeding,” they will say;
And gravely hand it to their mum
To take it to clean away
But let us speak of chocolate cake,
It must be frosted o’er;
They’ll devour three full slabs,
And calmly ask for more.
Oh, I do so always love to eat
With picky little pests,
Whose parents joy to make them
The most undesirable guests!

The call of the seas has always found an echo in me. Not being rich enough to roam in a private yacht, I have taken the poor man's way out. I swim across them. I have always been fascinated by the Indian ocean, whether at Mumbai, at Puri or at Gopalpur. I have swam in all these places and have felt the thrill. But the idea of swimming the Palk Strait did not occur to me until after I swam in the English channel. Steeped in the history and tradition of this nation, practically unconquered. teaming with hair-raising hazards, the sea between India and Sri Lanka had all the elements of challenge, danger and difficulty that tempted me. By the way, for preparation, I continued a strict and rigorous course of training which began in 1960. I also had to collect a comprehensive range of facts and information about this sea. Neither of these was easy. Despite all the information I had gathered, I soon found that very little was known about the Palk Strait, especially about the tides and currents. Everything about the English channel is known-there is the Channel Swimming Association, there are trained pilots there are wants to be hired, accurate weather forecasts, dependable tide tables and every other form of assistance was readily available. All that one needed was money. Here in the Palk Strait one has to find out firstly from where information could be obtained and then decide how much of it could be incorrect or misleading! |
