Futures and Options Vs Equity

How can one earn more in F&O compared to equity.
What if the price of that stock go below the future contract agreement?
What happens to the contract if i dont have enough money after market price is down?

u cant earn more, but u need less amount to earn the same amount of money in F&O than cash around only 10%
if the price of the stock go up or down u lose or gain that much amount, if u don’t have enough amount position will be squared off by your broker.
